/*
 * system-6.css — Macintosh System 6 built-in theme (ADR-188).
 *
 * Owner: @sharpee/platform-browser (a platform-shipped built-in theme).
 *
 * A *rich* theme: a `[data-theme="system-6"]` token override block targeting
 * the `--theme-*` contract consumed by the engine layer (engine.css), plus a
 * substantial flourish set — the genuinely distinct Macintosh System 6
 * window/menu/dialog chrome (striped title bars, 1-bit dithered scrollbars,
 * bitmap webfonts) that the token model alone cannot express. The chrome rules
 * stay scoped under [data-theme="system-6"] so they apply only when selected.
 *
 * Built-in themes ship with platform-browser under styles/themes/ and are wired
 * into a story by listing their id in `sharpee.themes`. The build copies this
 * file to dist/web/themes/system-6.css and its assets (the system-6/ dir, per
 * styles/themes/manifest.json) to dist/web/themes/system-6/, so the @font-face
 * URLs below resolve. ChicagoFLF + FindersKeepers provenance:
 * sakofchit/system.css (MIT, 2022).
 *
 * Load order (ADR-188): base.css → engine.css → THIS FILE → [author override].
