/* ═══════════════════════════════════════════════════════════════════════════
   Meltbox design system — Autogenic Labs brand (warm cream register).
   Dense, keyboard-first, IDE-grade. See BUILDING-APPS.md for usage.
   Principles: color encodes one comparative variable; band the chrome,
   foreground the content; stable layout (no bounce); 4px grid.
   Palette = brand/DESIGN.md warm cream register: neutrals + gold + semantics
   are CONSTANT across every theme; the ACCENT hue is the one variable a theme
   swaps. Accent = "alive/active/brand"; gold = sparkle / CTA only, never body
   or borders. No gradients, no glows, no halos — ever.

/* ═══════════════════════════════════════════════════════════════════════════
   THEME SYSTEM — Autogenic Labs brand model (one accent per surface).
   The active workspace owns the theme; the shell sets html[data-theme=<id>].
   Six themes = the brand accent family: green, coral, teal, blue, indigo
   (DEFAULT), violet. A theme swaps ONLY the accent slots — the warm-cream
   neutrals, gold, and semantics are CONSTANT everywhere. Every accent-derived
   role (--ok/"alive", --env-prod, --env-staging, --chart-1, focus rings,
   spinners, links, active nav, selected states, badges) reads from --accent,
   so a single hue swap recolors the whole surface.
   Base :root carries the shared (non-color) tokens + the cream neutrals + the
   DEFAULT indigo accent, so an un-themed document paints correctly (no flash).
   `light` is kept as an alias of the default for standalone briefs (brief.js
   sets data-theme="light" when none is present — do not remove).

/* ── iOS focus-zoom guard ──────────────────────────────────────────────────
   iOS Safari force-zooms the page when a focused text control's computed
   font-size is under 16px, and the zoom sticks after blur (pinching back out
   is fiddly). On touch devices, hold every text-entry control at 16px so the
   zoom never fires; fine-pointer devices keep the dense 12-13px sizing.
   !important is deliberate: control fonts are set by many per-page and
   per-component rules (often via the `font:` shorthand), and this guard must
   beat all of them, including later-loaded page styles. Do NOT solve this
   with user-scalable=no or maximum-scale on the viewport meta instead: that
   disables pinch-zoom, which is an accessibility violation. */
