/* ============================================================
   PGCS programme pages (T-742, T-752): a standalone theme, dark by default
   with a light scheme.

   The two token blocks above hold every colour: :root is the dark scheme
   (the default), html[data-scheme="light"] the light one. The BioCE shell's
   scheme toggle sets data-scheme="light" on <html> (lang-prepaint.js sets it
   before first paint from localStorage 'bioce-scheme'); no attribute means
   dark. Change a colour in BOTH blocks; every rule below reads it through
   var(), and the tests refuse a colour literal anywhere else in this file.
   deploy/check_contrast.py checks the text pairs of both schemes against
   WCAG 2.1 AA (4.5:1) and the pressed planner filter ring against 3:1.

   --brand / --brand-hover fill buttons, tags and the live rows (white
   --on-brand text). --brand-text is accent TEXT (headings, links, badges):
   a light wine tint on the dark scheme, the brand itself on the light one.
   --brand-line paints accent rules, markers and borders; --brand-edge
   outlines the primary button on the dark scheme only.

   T-816 (owner 2026-10-21: "black, real black, not red"): the dark --bg is
   pure black and --bg-2 a near-black neutral for cards and bands; the text
   tokens did not move. The pages are LIGHT by default: both carry
   data-scheme="light" on <html> in the markup (the shell reads it as the
   page default and shows Light), and lang-prepaint.js removes it before
   first paint when the stored bioce-scheme is dark. The PGCE page keeps
   dark as its default. Any new dark value must keep check_contrast.py at 28/28.

   The BioCE shell header (/assets/bioce-shell/shell.css) keeps its own
   tokens and is not styled here.
   ============================================================ */

/* Form controls and scrollbars follow the scheme: dark by default whatever the OS prefers (the
   pages' <meta name="color-scheme"> says "dark" only), light once the shell sets data-scheme.
   Only <html> carries data-scheme, so the bare attribute selector targets the same element as
   html[data-scheme="light"] and outranks `html`; it keeps that selector to the one token block. */
