   birewa.com — Harmattan, recoded as pure static CSS. No build.
   Concept: warm near-black ground, mineral dust accents, one cold signal.
   Edit a colour once here (--color-*) and it changes everywhere,
   including the canvas field which reads --field-* at runtime.

/* ---- Tokens ------------------------------------------------------
   Two themes, same Harmattan identity. Light is the base :root palette
   ("paper" — dust on cream, warm ink); dark is Harmattan's original near-
   black. Which one shows:
     - no explicit choice  -> follows the OS (prefers-color-scheme)
     - [data-theme="light"|"dark"] -> explicit choice from the toggle,
       stored in localStorage, wins in both directions.
   The canvas field reads --field-* at runtime, so it re-themes for free —
   except it only ever runs in dark (see js/main.js): additive "glow"
   particles read as embers on near-black and as a washed-out mess on
   paper, so light keeps the calmer poster gradient with no live canvas.
