The original hardening got the structural selectors right, but the
labs/kits/book sidebar still had two divergences from the instructors
reference: (a) section headers and leaf links rendered with the same
muted color (no hierarchy) because the section-header rule only matched
the chevron `<a class="sidebar-item-toggle">` and missed the section
text `<a class="sidebar-link text-start">`, and (b) the active-state
rule colored the text in the accent color rather than white on a subtle
accent tint, so active links read as loud accent fills instead of the
clean instructors look.
Changes per file:
* labs/, kits/: extend section-header selector list to include
`a.sidebar-link.text-start`; drop `font-weight: 400 !important` from
the leaf rule so the section-header weight (600) wins on elements
matching both; move active-state color/background/weight into the
high-specificity `#quarto-sidebar` guard block to beat Bootstrap's
default `.sidebar-link.active { color: var(--bs-primary) }`.
* book/quarto/: same treatment, plus include `.part-divider` in the
section-header selector list to keep the part-divider hierarchy.
* tinytorch/quarto/: same active-state hardening, plus rename
`$accent` → `$accent-dark` throughout (the theme partial
shared/styles/themes/_theme-tinytorch.scss declares both variables;
since Quarto auto-`!default`s every scss:defaults declaration, the
reassignment of `$accent` here was silently ignored and rgba calls
resolved with the light #D4740C value). Drop the unused
`$link-color-dark` definition that referenced `$accent-dark` from
scss:defaults — Quarto hoists user defaults above shared partial
defaults, so `$accent-dark` isn't yet defined when that line runs.
Rules in scss:rules resolve `$accent-dark` correctly because rules
are processed after all defaults are merged.
Verified with Playwright probes on /vol1.html (slides), /index.html
(labs, kits), /big-picture.html (tinytorch), /api-stability.html
(mlsysim), /foundations-syllabus.html (instructors): all six now show
white active text on rgba(accent, 0.15) tint, weight 500, with bright
section headers (#e6e6e6) at weight 600 and muted leaf links (#888888
or #cbd5e1).
Extends PR #1633's instructors fix to the rest of the Quarto ecosystem.
Quarto renders floating sidebars with `<a class="sidebar-link">` and
`<a class="sidebar-item-toggle">` directly (not nested inside an
`.sidebar-item a` wrapper), so the legacy selector missed all real DOM
nodes.
Sites updated:
* slides, interviews, tinytorch/quarto, mlsysim/docs: full hardening
(toggle, leaf-link, active-state, search input, TOC rail).
* labs, kits, book/quarto: added missing search-input theming
(core sidebar and TOC fix already present from earlier work).
Each site's accent color is preserved: indigo for instructors and
interviews, pink for slides, amber for tinytorch, cyan for mlsysim,
teal for kits and labs, crimson for book.
Quarto re-loads the light syntax-highlighting CSS via a "quarto-color-scheme-extra" link that the color-toggle JS never disables, so it overrode the dark theme's code-block background and token colors. Force the github-dark palette and dark `#2c2c2c` background on `div.sourceCode pre.sourceCode` with !important, and split highlight-style into a light/dark pair so Quarto emits the dark syntax bundle.
The 26-token `context` array was authored as inline code under a list
item, so it rendered as a single non-wrapping line and forced
horizontal scroll on the whole page. Move it into a fenced `text` code
block with the array broken across three lines — the block scrolls
within its own width and the page no longer overflows.
Two bugs in contents/raspi/image_classification/image_classification.qmd:
1. Size unit typo: cifar10.tflite was described as "674MB" but the
original .keras model is 2.0MB and 1/3 of that is ~674KB. 674MB
would be larger than the entire ImageNet training set -- clearly
a unit typo that misleads students about model compression ratios.
2. Broken bash command for picamera2 venv path setup: the redirect
target path was split across two lines with a stray newline after
"python3.11/", turning it into two invalid shell commands:
- redirecting stdout to a directory (error)
- trying to execute "site-packages/system_site_packages.pth" (error)
Merged the path onto one continuation line.
Adds the Tier B (lite) versioning pattern to all three Quarto-only
sites in one commit — they have identical shape, so fragmenting would
add review burden without isolation benefit.
For each project:
- workflow_dispatch inputs: release_type/description/site_only/
explicit_version/confirm. Same shape as Tier A workflows so
operators see one consistent UI across the monorepo.
- New `prepare:` job calls _release-prepare.yml with tier=B and the
project's previous_tag_pattern.
- New manifest emit step before deploy: hashes the project's content
directory (excluding _build, .quarto, etc.) and writes
release-manifest.json into the build output. URL convention
matches the deploy path: /kits/, /labs/, /instructors/.
- New create-tag job: tags <project>-v<release_id> on success.
Tier B intentionally skips AI-generated release notes — the
description plus auto-generated commit list (where available) is
sufficient given the rapid iteration cadence and lower citation
stakes than book/staffml/tinytorch/mlsysim.
- Quarto _quarto.yml: <meta name="release-manifest"> in
include-in-header and shared/release/release-pill.html in
include-after-body.
No changes to Marimo notebook structure (labs), Quarto build commands,
PDF builds, or any project's content files.
Iterates on the post-merge 404 redesign across all 8 sub-sites:
- SVG roofline-plot fonts bumped for readability without changing
layout: axis labels 9.5pt to 14pt, region labels 9.5pt to 14pt,
title and "your page (404)" annotation 11pt to 16pt.
- Random-joke font shrunk from 1.6rem to 1.3rem (1.1rem on mobile)
so the joke no longer dominates the SVG above it.
- Removed the static "Looks like this page slipped past our load
balancer" subline from 6 sub-sites — it read as a competing static
joke alongside the random rotation. Slides and instructors keep
their informational sublines.
- Joke pool tightened 97 to 79 via a strict ML-systems-centric test:
if you could swap "page" for any generic web/ops resource and the
joke still works, cut. Cuts removed the H&P canonical material
(Amdahl's Law, TLB miss, Dennard scaling, false sharing, fat-tree
topology) that is general computer architecture rather than ML
systems specifically. 19 borderline jokes were rewritten to anchor
punchlines in concepts only ML practitioners decode (KV cache,
gradient AllReduce, prefill, ZeRO, speculative-decode acceptance,
1F1B schedule, ridge point, BPE merges).
Replace the inline-game 404 across all 8 sub-sites with a unified
design: roofline-plot illustration, random pick from a 97-joke
editorial-curated pool, dual CTA (home + playground), and a
GitHub-issue-backed contribute link for community submissions.
The joke pool was curated through a multi-agent editorial process:
4 generators (each with a different ML systems lens) produced 240
candidates; 5 reviewer personas (architect, NLP researcher, production
engineer, undergrad, copy editor) scored each; the synthesizer kept 92
surviving jokes plus 5 new canonical-architecture additions (Amdahl,
TLB, Dennard, false sharing, fat-tree topology) the architect flagged
as missing from the H&P-tradition canon.
Self-contained CSS with prefers-color-scheme: dark adapts to host
themes without coupling to each sub-site's bespoke styling. SVG
follows the book's semantic palette (blue memory-bound slope, green
compute roof, MIT red error annotation). Per-site navigation
preserved across all sub-sites.
Adds .github/ISSUE_TEMPLATE/404_joke.yml so contributions arrive
structured (joke text, theme dropdown, license checkbox) and
auto-tagged (site, 404-joke, good-first-issue) for triage.
- Added 'KV Cache Packer' to teach PagedAttention and KV fragmentation
- Added 'Cluster Commander' to teach Slurm scheduling and fleet fragmentation
- Registered all 14 games in the runtime registry
- Fixed WebGL rendering loops to avoid performance overhead and crashes
- Updated 404 pages across all workspaces to route to the new games Playground
- Overrode default Quarto 'S' search shortcut to Shift+? to free up typing controls
Align public README and site messaging around the curriculum components, adoption paths, and current early-release status so newcomers can move from reading to building, deployment, practice, and teaching.
Before: four Quarto sites each shipped their own copy of the
`.sidebar-navigation .sidebar-item a` rule block, each hard-wired to a
different accent variable ($accent, $kits-accent, $colabs-accent,
$mlsysim-accent). Plus one 1350-line orphan file
(book/quarto/assets/styles/style.scss) that was referenced nowhere and
carried yet another copy of the same rules.
After: every site imports shared/styles/partials/_sidebar.scss once.
Each site aliases $accent to its own site-accent (book does it via
themes/_theme-harvard which sets `$accent: $brand-crimson`; kits/labs/
mlsysim already had `$accent: $site-accent` at the top of their
style.scss), so the partial's accent-keyed hover/active states resolve
to the right color per site without needing a per-site rule copy.
Files:
- shared/styles/partials/_sidebar.scss
(unchanged in this PR — already is the canonical form after #1514)
- book/quarto/assets/styles/_base-styles.scss
replace ~40 lines of local sidebar rules + .part-divider with
`@import '.../partials/sidebar'`
- book/quarto/assets/styles/style.scss
DELETE (1350 lines, zero build references — confirmed by grep
across _quarto*.yml, Makefile, .sh, .py, .js)
- kits/assets/styles/style.scss
replace local sidebar rules with partial import; keep the
site-specific `.sidebar-title` rule (not part of the shared shape)
- labs/assets/styles/style.scss
replace local sidebar rules with partial import
- mlsysim/docs/styles/style.scss
replace local sidebar rules with partial import; the
.sidebar-navigation > .sidebar-menu-container dividers below
are site-specific and stay
Net: +23 / -1531 lines. Behavior is identical (the partial was already
tightened to these same values in PR #1514, so this is a
refactor-not-redesign). slides and instructors already had no sidebar
overrides and are not touched.
TinyTorch was already importing the partial directly and is unchanged.
The ecosystem now has one sidebar rule block, in one file, controlling
every Quarto site.
Every site's announcement bar now follows one template:
Line 1 — identity + primary CTA (what is THIS site)
Line 2 — the book (or, on book sites, the other volume)
Line 3 — "Alongside the book:" sibling row (3 most-relevant verbs)
Line 4 — newsletter
The book is the anchor of the curriculum; every other site is a verb
applied to it — TinyTorch (build), Hardware Kits (deploy), MLSys·im
(simulate), Labs (explore), Slides + Instructors (teach). Making that
shape visible in every bar turns nine independent sites into chapters
of one curriculum.
Removed stale copy: "Happy New Year!" on kits + labs, "coming in 2026"
on labs (we are in 2026; replaced with "Coming Summer 2026"), TinyTorch
v0.1.10 single-line release notice (belonged in a release changelog,
not the always-visible nav bar).
Normalized outbound links: /book -> /vol1/ and /vol2/, consistent
trailing-slash hygiene on every URL. Newsletter link points to
https://mlsysbook.ai/newsletter/ (the actual Quarto page) instead of
#subscribe (which only resolves on the landing page).
The landing site (mlsysbook.ai) uses a 5-line variant that covers all
four learner verbs + the teacher-tools row; every other site uses the
4-line form.
StaffML is a Next.js app, not a Quarto site, so its banner is out of
scope for this PR and will ship as a separate React component change.
* polish(tinytorch/diagrams): align 23 Lab Guide SVGs with book style guide
The hand-authored diagrams under tinytorch/quarto/assets/images/diagrams/
were drifting from the ML Systems SVG style guide — they used Tailwind
CSS greys and custom oranges instead of the book palette. This made them
visually clash with the canonical big-picture-module-flow.svg (under
assets/images/svg/) and with every other diagram in the textbook.
Normalize to book style:
- Fills: #f4f5f7, #f8f9fa, #e5e7eb → #f7f7f7 / #bbb (book neutrals)
- Text: #1f2937, #6b7280 → #333 / #999 (book text hierarchy)
- Arrows: #9ca3af → #555 (book neutral stroke)
- Accent orange: #fff1e8 / #ff8246 → #fdebd0 / #c87b2a (book routing)
- Corner radius: rx="2" → rx="4" per style-guide standard
- Stroke width: flat "1" → "1.2" (secondary tier per style guide)
- Section titles: font-size="11" (bold) → "12" per style-guide headers
No content, layout, or positional changes — only style-token swaps.
All 23 SVGs re-validated as well-formed XML.
Side effect: the orphan diagrams/00_big-picture-module-flow.svg is also
normalized. The canonical big-picture is under assets/images/svg/ and
was already book-styled (not touched by this pass).
* polish(tinytorch/01_tensor): port Cache Tiling systems callout from ABOUT.md
The stashed work from the tinytorch-updates branch included a Cache
Tiling "Systems Implication" callout for Module 01, but it lived in
tinytorch/src/01_tensor/ABOUT.md — a path that was retired when the
module docs consolidated into tinytorch/quarto/modules/. The companion
"Contiguous Memory & Strides" callout from the same stash already made
it over during the consolidation; this one got left behind.
Insert the callout right after the matmul O(n³) explanation (the
natural bridge into "why does the naive loop lose to BLAS?"), and
before the Shape Manipulation section. Progressive-disclosure check:
every concept the callout introduces (cache misses, BLAS, O(n³) vs
O(n²)) is already on the page or introduced inline in the callout
itself (Memory-Bound / Compute-Bound are defined parenthetically).
The pattern matches the existing book-style sidebar on line 587.
* deps: bump TypeScript 5→6, @types/node 20→25, ipykernel 6→7
Resolves 9 stale Dependabot PRs (#1494, #1497, #1490, #1491, #1479,
#1477, #1475, #1467, #1454) whose package-lock conflicts blocked
auto-rebase.
VSCode extensions: bump TypeScript devDep to ^6.0.3 and @types/node to
^25.6.0 across book-ext, mlsysim-ext, labs-ext, kits-ext, tinytorch-ext.
Regenerate lockfiles.
TypeScript 6.0 no longer auto-includes ambient @types packages; add
explicit "types": ["node", "vscode"] to each tsconfig so
child_process / fs / Buffer / vscode API types continue to resolve.
All 5 extensions now compile clean with TS 6.0.3 + @types/node 25.6.0.
TinyTorch: bump ipykernel floor to >=7.2.0 in pyproject.toml,
requirements.txt, and binder/requirements.txt.
Add `text` language tag to 25 unlabeled fenced code blocks across the
public-facing READMEs. Mostly directory-tree listings, all-contributors
bot instructions, and pseudo-output ASCII blocks — none were getting
syntax highlighting anyway, but the explicit tag silences markdownlint
MD040 and signals intent ("this is plain text, not a forgotten lang").
GitHub's github-markdown-css applies:
.markdown-body table { display: block; width: max-content; max-width: 100%; }
The HTML width="100%" attribute is a presentational hint with lower
specificity than the class selector, so tables with short cell content
were sizing to max-content and not stretching to fill the column.
Tables with long sentences per cell stretched fine, masking the bug.
Add inline style="width:100%" (specificity 1,0,0,0) which overrides
the class-selector rule. Keep width="100%" attribute as a fallback for
non-GitHub renderers (VSCode preview, GitLab, plain HTML viewers).
54 tables updated across 10 READMEs + the two contributor-sync scripts
that regenerate auto-managed tables.
The sub-project READMEs used an old-school nested-table card design
with hardcoded bgcolor="#ffffff", "#cfd6dd", "#eef2f7" plus deprecated
HTML4 attributes (cellpadding, cellspacing, border). It looked good in
light mode but produced harsh white islands in GitHub's dark theme,
which is what most readers see today.
Across 11 sub-READMEs:
- Strip the card wrapper so data tables are just clean
<table width="100%"> with semantic <thead>/<tbody>. Headers keep
their column widths; bgcolor/valign/zebra-stripe cruft is removed
(GitHub provides its own theme-aware striping).
- Convert the early-release callouts (and mlperf-edu's two-tier
status block + "source of truth" note + interviews' two info boxes)
to GitHub-native > [!NOTE] / > [!WARNING] / > [!TIP] callouts.
These are theme-aware, get proper icons, and render correctly in
light AND dark mode.
Net result: 528 lines of HTML cruft removed, 230 lines of clean
markdown added. Visual identity is preserved (callouts still stand
out, tables still stretch full-width) while becoming dark-mode safe
and consistent with the main README.
Add `width="100%"` to every HTML content and contributor table across all
project READMEs so they render full-width on GitHub instead of collapsing
to natural content width. Cell-level `width="X%"` percentages were already
in place but only take effect once the table itself has an explicit width.
Also update the contributor-sync scripts so the auto-generated tables stay
consistent on the next bot run:
- .github/workflows/contributors/generate_main_readme.py
- .github/workflows/contributors/generate_readme_tables.py
Scope: 27 files, 85 tables. Sub-project READMEs that already use the
"card" pattern (labs/, kits/ content sections with <table width="98%">
wrappers) are intentionally untouched.
Brings the TinyTorch lab guide's Quarto project in line with
book/quarto/, the only other in-tree Quarto publication that builds
both web and PDF outputs from a single source. The previous name had
three redundancies:
- already under tinytorch/, so "site-" prefix wasn't disambiguating
- also produces the PDF lab guide, so "site-" was misleading
- the top-level site/ dir made "site-quarto" read as "the site's
quarto config" rather than "the tinytorch site, in quarto"
After this rename the convention is straightforward:
book/quarto/ -> the textbook (web + PDF)
tinytorch/quarto/ -> the TinyTorch lab guide (web + PDF)
mlsysim/docs/ -> mlsysim API reference (kept as docs/, since it
really is API reference, not a publication)
Touches 7 GitHub workflows, both .gitignore files, the rename target's
own self-references (Makefile, _quarto.yml configs, STYLE.md,
measure-pdf-images.py), and 6 copies of subscribe-modal.js plus a few
shared scripts/configs whose comments documented the old path.
Verified: rebuilt pdf/TinyTorch-Guide.pdf (2.1M) cleanly from the new
location with 'make pdf' from tinytorch/quarto/.
- Add wrap_readme_data_tables.py to frame <table>+<thead>/<tbody> blocks in a
98% width panel (#cfd6dd border, #eef2f7 headers, zebra body rows where
applied manually in converted tables).
- Apply wraps to book, kits, labs, slides, tinytorch; tbody wraps for kits
docs/related and instructors overview.
- Convert remaining Markdown tables in mlsysim, mlperf-edu, and interviews to
the same HTML pattern; replace StaffML markdown callouts with HTML panels.
- Add thead rows to kits/instructors body-only tables for clearer hierarchy.
Quarto's resource-copy step preserves symlinks rather than dereferencing
them, which breaks both local builds (AlreadyExists on the second pass)
and gh-pages deploys (relative symlink targets fall outside _build/).
And Sass resolves @import relative to the importing file's physical
location, not the symlink target. So symlinks inside the resource path
are not a viable dedup mechanism.
Instead, keep real file copies in each consumer subsite and enforce
dedup at edit time with shared/scripts/sync-mirrors.sh:
- bash shared/scripts/sync-mirrors.sh # propagate canonicals
- bash shared/scripts/sync-mirrors.sh --check # CI: fail on drift
Mirror map (source | mirrors):
shared/scripts/subscribe-modal.js -> {site, book/quarto, labs, kits,
mlsysim/docs}/.../subscribe-modal.js
Intentional non-mirrors (left untouched, customized variants):
tinytorch/site-quarto/assets/scripts/subscribe-modal.js (TinyTorch-branded)
tinytorch/site/_static/subscribe-modal.js (legacy Sphinx)
Also dedupe the SocratiQ widget bundle via a symlink (safe here because
book/tools/ sits outside any Quarto project, so the resource walker
never touches it):
book/tools/scripts/socratiQ/bundle.js -> ../../../quarto/tools/scripts/socratiQ/bundle.js
The shared canonical (book/quarto/tools/scripts/socratiQ/bundle.js) is
the version actually referenced and served in production.
- Replace inline Google Fonts <link> tags in all 8 site configs with
a single `- file: shared/config/site-head.html` reference, so fonts
(Inter 400-800, JetBrains Mono) and Font Awesome are inherited from
one shared file instead of duplicated across every _quarto.yml
- Add missing Inter weight 800 (was only in site-head.html, not configs)
- Add carousel CSS + JS for MLSys·im landing page (arrows, dots, slides,
auto-rotation, keyboard nav) — fixes non-functional < > buttons
Replace duplicated navbar/mobile responsive rules in satellite sites
(instructors, kits, labs, mlsysim, slides) with a single import of
shared/styles/partials/_mobile.scss. Removes ~169 lines of copy-pasted
CSS that would drift out of sync when the shared partial is updated.
- instructors: remove rogue desktop padding, add _mobile import
- kits: remove ~50 lines of duplicated mobile rules, add _mobile import
- labs: remove ~55 lines of duplicated mobile rules, add _mobile import
- mlsysim: remove ~55 lines of duplicated mobile rules, add _mobile import
- slides: add _mobile import (had no mobile rules before)
Every subsite now sets $accent to its brand color and imports
shared/styles/partials/_navbar.scss instead of duplicating the
~40-line navbar block locally. Single source of truth for link
color, hover/active states, brand image height, icon-collapse
media query, and color-scheme toggle.
Drift fix: before this, instructors had font-size: 0.9rem +
weight 500 (making navbar look smaller than peer sites) and
slides had no navbar CSS at all (fell back to Bootstrap defaults).
Both now match the ecosystem.
Also renames $accent in labs/style.scss (previously hot pink
#e94560, used only by .coming-badge) to $coming-badge-pink to
free $accent for the ecosystem convention.
Net: -168 lines of duplicated SCSS across 6 files.
Adds a one-line pointer inside the existing Laboratory Development
callout, routing readers from the kits landing page to the Companion
Books section on the Instructor Hub. Keeps the kits site focused on
hardware and lab content; the curated book listing stays canonical
on the instructor hub.
- Sync translated READMEs (ja, ko, zh) with renamed workflow files and
add Slides, Instructors, StaffML badges
- Fix Docker Windows README paths and workflow reference
- Rewrite book/tools/scripts README to point to Binder CLI first
- Update kits badge from kits-publish to kits-validate
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Site covers were 867×1031 (cropped) vs the book's canonical 867×1110.
Replaced with full-resolution copies so author name is visible.
Made card background fully opaque to prevent neural background bleed-through.
Tested: Quarto metadata-files merge DOES inherit responsive properties
(background, pinned, collapse, collapse-below) from navbar-common.yml.
Local configs only need logo, search, title, and site-specific left: items.
Removed 4 redundant lines from each of: mlsysim, labs, kits, instructors, site.
Single source of truth: shared/config/navbar-common.yml
Update vol1/vol2 hardcover mockup images with boosted colors. Rename
cover_image_title files to hyphenated cover-image-title for consistency.
Remove old non-vol-suffixed duplicates. Update all config and index
references to use vol-specific filenames.

The moat is the vault data, not the viewer. MIT for the app encourages
adoption and contributions. Proprietary for the corpus protects the IP.
Architecture:
- Merge landing, about, community, newsletter into one site/ project
- Move navbar-common.yml to shared/config/ (used by 12 configs)
- Create shared/config/footer-site.yml for centralized footer
- Create shared/scripts/subscribe-modal.js as canonical copy
- Single _quarto.yml replaces 4 independent configs
- One site_libs/ copy replaces four
Features gained:
- Google Analytics on ALL hub pages (was only on book volumes)
- Subscribe modal on landing page (was missing)
- Centralized footer with consistent links
Workflows updated:
- site-preview-dev.yml: matrix strategy → single build job
- site-publish-live.yml: loop over subsites → single build + deploy
- sync-newsletter.yml: builds from unified site project
- publish-all-live.yml: removed stale subsite input
- rewrite-dev-urls.sh: added --shallow flag for unified builds
All 12 navbar-common.yml references updated:
book vol1/vol2, site (unified), slides, instructors, interviews,
kits, labs, mlsysim
Replace the generate-navbar.py script approach with direct metadata-files
references to navbar-common.yml. Quarto natively merges navbar arrays,
so site-local dropdowns defined inline in each _quarto.yml get appended
to the shared navbar automatically.
- Delete generate-navbar.py script (no longer needed)
- Delete all _navbar-generated.yml and _navbar-local.yml files
- Each subsite now references ../book/quarto/config/shared/html/navbar-common.yml
directly via metadata-files
- Sites with local dropdowns (slides, instructors, mlsysim) define them inline
in their _quarto.yml navbar.left — Quarto merges with the shared left items
- Zero tooling, zero generated files, zero maintenance scripts
Single source of truth for the navigation bar in navbar-common.yml.
New 5-dropdown structure: Read | Build | Teach | Community | About.
- Add generate-navbar.py script to merge shared + site-local dropdowns
- Add _navbar-local.yml for slides, instructors, mlsysim (site-specific menus)
- Generate _navbar-generated.yml for all 6 subsites (committed, no CI changes needed)
- Strip hardcoded navbars from all _quarto.yml configs (landing, vol1, vol2, slides,
instructors, mlsysim, kits, labs, newsletter)
- Add community/ and about/ paths to rewrite-dev-urls.sh for dev preview
To update navbar: edit navbar-common.yml, run generate-navbar.py --all, commit.
Refresh top-level README with clearer volume naming, HTML branch
table, and consolidated support section. Replace ASCII art with
SVG diagrams in tinytorch milestones and labs. Streamline slides
and kits READMEs. Remove retired challenges/ directory.
