/* RustIO admin — Tailwind input.
 *
 * This file is the SOURCE. The compiled output lives at
 * `rustio-core/assets/static/css/admin.css` and is baked into the
 * binary via `include_str!`. Run `make css` to rebuild after editing.
 *
 * Hybrid class strategy: semantic component classes live in
 * `@layer components` so projects overriding admin templates by class
 * name don't silently break. Utility classes are used directly inside
 * templates for one-offs.
 *
 * Phase 2 — Design system foundation. Source of truth:
 * `docs/design-system.json`. Mirrored in `tailwind.config.js`.
 * Semantic colour tokens are CSS custom properties so the same
 * Tailwind utility (`bg-surface`, `text-accent`) adapts to the active
 * theme (default light / `<html class="dark">` / `<html class="theme-rust">`).
 * Templates haven't been refactored yet — Phase 7a/2 component
 * classes still reference `bg-rust`, `bg-paper`, `bg-metal-*`. Those
 * legacy colour names live alongside the semantic tokens until the
 * template-refactor sub-phase ships.

  /* Inline `<code>` chip — Phase 3/b-0 retune for exact visual parity
   * with the inline pattern that lives in 8 templates today
   * (`bg-paper px-1.5 py-0.5 rounded text-small font-mono`).
   *
   * Display stays inline (no `inline-block`) so the chip flows with
   * surrounding sentence text. Padding + radius use Tailwind
   * defaults. No border. `bg-paper` is the legacy warm-paper neutral,
   * kept here so the chip matches existing card/module backgrounds.
   *
   * Note: `text-small` matches 5 of 8 inline occurrences. The three
   * sites that currently use `text-caption` will shift +0.5px on
   * the refactor sweep — imperceptible at chip scale. Documented as
   * an explicit, accepted deviation per the user spec ("13px
   * equivalent"). */
