/* The Station — 00-base: the music-app token contract (DARK-FIRST), the shell,
   the stations home (Daily Mix + list + domain grid), the toast and the
   persistent mini-player.

   Dark is the DEFAULT (:root) — a near-black ground, one vivid iris accent, big
   type. A light theme is fully designed under @media (prefers-color-scheme:
   light). The accent evokes a music player's mechanics without borrowing any
   streaming brand's trade-dress colours; each domain station carries its OWN
   hue (set inline via --hue) so the home grid reads like a wall of records. */

/* The Station — 05-themes: the THEME WARDROBE (6 dark-native packs), the
   theme-picker chrome, and the Spotify-feel pass (heavier type, hue-bleed
   page headers, art-first domain shelves with a play FAB, and a Spotify-style
   mini bar). Loads AFTER 00-base (globbed 05- sorts between 00- and 10-), so a
   pack's token overrides win the equal-specificity tie against the :root /
   prefers-color-scheme defaults purely by source order.

   Mechanism: documentElement carries data-st-theme, stamped at boot from the
   DEVICE-LOCAL localStorage key wv:st:theme (Store prefix "wv:" + "st:theme").
   That key is deliberately ABSENT from ST_SYNC_KEYS (70-sync.js) — the theme
   is per-device, never a synced preference, never in a PUT body. Default when
   unset is "encore" (the dark Spotify pack). "iris" is the ONE id with no
   block here on purpose: data-st-theme="iris" matches nothing, so the original
   auto light/dark :root wardrobe stays byte-for-byte intact — the pixel-parity
   contract, exactly like tenet's "standard" skin.

   Each pack overrides the FULL colour-token contract coherently (bg through
   accent), keeps body ink at or above 4.5:1 on its ground, and declares
   color-scheme: dark so native form controls follow. Shadows, radii, fonts and
   measures are inherited from :root and never re-declared. */
