📝 WalkthroughWalkthroughThe change adds persistent dark and light theme switching. It initializes theme attributes early, adds a navbar toggle with cross-tab synchronization, removes hardcoded dark-theme containers, and defines light-theme styles across the site. ChangesTheme toggle
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds theme switching and persistence, but unsupported saved theme values can leave users with an incorrect theme state, while some light-theme controls and link hovers have insufficient contrast. The change is mergeable with explicit owner follow-up on these bounded accessibility and persistence issues. Sequence Diagram(s)sequenceDiagram

icon and hover colors that meet the required contrast against the white navbar,
and replace the inherited focus-visible outline color with a sufficiently
contrasting color. Preserve the existing sizing, shadow, transform, and
interaction behavior.

In `@assets/scss/_styles_project.scss`:
- Around line 1125-1134: Update the .td-search__input placeholder color in
.td-navbar .td-search to a darker value that meets WCAG 2.1 AA’s 4.5:1 contrast
requirement against `#f3f4f6`, such as `#4b5563`.
In `@layouts/partials/head.html`:
- Around line 40-43: Normalize theme values to only “dark” or “light” in
layouts/partials/head.html lines 40-43 before setting either document attribute,
falling back to the existing default for invalid persisted values. In
layouts/partials/navbar.html lines 395-429, update applyTheme to normalize
incoming values before setting attributes or persisting them.

Fixes #1069
Problem:
Previously, the documentation site had no dark/light theme toggle button in the navbar, and the site was hardcoded strictly to dark mode without any option to switch to a light theme.
Solution:
localStoragewith multi-tab synchronization.<head>to prevent FOUC (flash of unstyled content) on page load.Before vs After
