/* 1b. Light palette
   ------------------------------------------------------------
   WHAT WAS HERE BEFORE, AND WHY IT WAS A BUG.
   This file shipped a bare `@media (prefers-color-scheme: light) { :root
   { … } }`. That block is live for a light-OS visitor who explicitly
   chose DARK — and because page sheets are linked from
   `{% block extra_head %}`, i.e. AFTER theme.css, its `:root` (0,1,0)
   also beat theme.css's own dark `:root` on source order. The result was
   a bright island inside dark chrome, which is the exact regression
   theme.css's THEMING banner documents.

   The fix is two-part and needs BOTH halves: the media block's interior
   is now scoped to `:root[data-theme="auto"]`, and the same values are
   spelled out again under `:root[data-theme="light"]` for the explicit
   opt-in. Re-guarding alone would leave a chosen-light visitor dark.

   The values cannot be shared through an indirection — the contrast
   sweep in tests/test_static/test_theme_pages_a.py resolves them to
   opaque hex — so KEEP THE TWO BLOCKS IN SYNC. A test does too.
   `@media` adds ZERO specificity, which is why the scoping, not the
   ordering, is what makes this safe.
