📄 Description

Summary

Two scoped fixes to labs/assets/styles/dark-mode.scss for the Co-Labs site in dark mode:

  • Navbar dropdown panels (Teach / Prepare / Connect): Bootstrap's default .dropdown-menu keeps its light surface on the dark navbar, and items inherit the global teal link color — combined, the popover is unreadable. Adds a dark surface plus item, divider, and header styling.
  • Landing-page Lab Inventory headings: labs/index.qmd ships an inline <style> block that hard-codes #1e293b !important on .volume-heading and .cluster-heading, making "Volume I: Foundations", "Volume II: At Scale", "I. Foundations", "II. Build", "III. Optimize", "IV. Deploy", and "Capstone" invisible on the dark body. Overrides are scoped under html[data-bs-theme="dark"] so they outrank the inline rules without piling on more !important.

Lab cards keep their white background in dark mode by design, so the in-card title / question colors were left untouched — only the headings sitting on the dark page background changed.

Test plan

  • quarto preview the labs site (or labs/tools/build_site.sh) and toggle dark mode.
  • Open each navbar dropdown (Teach, Prepare, Connect) — items and hover states must be readable on a dark panel.
  • On the landing page in dark mode, verify "Volume I: Foundations", "Volume II: At Scale", and every cluster heading (I. Foundations, II. Build, III. Optimize, IV. Deploy, Capstone) plus their · Labs 00–04 meta suffixes are readable.
  • Light mode is unchanged (overrides are gated on [data-bs-theme="dark"] / the dark-mode SCSS bundle).
