Convert all remaining lowercase 'x' used as multiplication (e.g.,
"1000x faster") to $\times$ across 17 vol2 chapters. These were
flagged by the new lowercase_x_multiplication validator check.
Simplifies the validator regex from a fragile word-list approach to a
broader pattern matching digit-x-lowercase (e.g., \dx\s+[a-z]) which
naturally excludes hardware counts (8x A100) and hex literals (0x61).
Includes the conversion script in _archive.
Convert all Unicode × (U+00D7) to LaTeX $\times$ in prose, tables, and
math contexts across both volumes. Unicode × is preserved only inside
fig-alt text for accessibility screen readers. One instance inside a
plain markdown backtick code span (frameworks.qmd) was reverted to
Unicode × since LaTeX doesn't render in code spans.
Updates validate.py with a new lowercase-x-as-multiplication check and
refines the latex_adjacent warning to distinguish _str variables (safe)
from raw inline Python. Updates validate_inline_refs.py comments to
reflect the new convention. Includes the conversion script in _archive.
Integrate figure rendering into the binder CLI so plots can be previewed
without a full Quarto build. Extracts Python code blocks with fig-* labels
from QMD files, renders them to PNG, and outputs a browsable gallery at
_output/plots/<chapter>/. Also fixes the package import chain so `binder`
works correctly as an installed entry point.
- Add book/cli/commands/render.py with RenderCommand class
- Wire into main.py with help table entry and command dispatch
- Add matplotlib>=3.7.0 to pyproject.toml dependencies
- Add book/quarto/_output/ to .gitignore
- Archive standalone render_figures.py to _archive/
Remove redundant ml_ prefix from ml_workflow chapter files and update all
Quarto config references. Consolidate custom scripts into native binder
subcommands and archive obsolete tooling.
