/* ── Design Tokens ────────────────────────────────────────────────
   Two themes share one token contract, so every component below is
   written once and themes for free.

   LIGHT IS THE DEFAULT. It lives on `:root`, which means a page
   renders light even before the theme bootstrap script runs — and
   still renders light if JavaScript never runs at all. Dark is an
   opt-in override on [data-theme="dark"].

   Order matters: the dark block must come AFTER this one. Both
   selectors have the same specificity, so when data-theme="dark" is
   present the later block is what wins.

   Naming note: --white means "primary text", not the colour white.
   It inverts with the theme. For things that must stay literally
   white regardless of theme, use --on-accent or --plate.
   ────────────────────────────────────────────────────────────── */

/* ── LIGHT THEME (default) ────────────────────────────────────────
   Warm paper neutrals rather than pure grey, so the orange brand
   reads as intentional instead of accidental. The accent darkens to
   #C4430D (5.0:1 on white) so accent-coloured text and filled
   buttons both clear WCAG AA — #FF6B35 only manages 2.9:1 on white
   and stays reserved for decorative washes via --brand.
