/* SIDOF24 Publisher — Material Design 3 token layer (M5-T01).
 *
 * Hand-rolled MD3 tokens + the foundational app-shell classes. We adopt Material 3 as
 * a CSS token layer (option A, decided 2026-06-18) rather than the @material/web custom
 * elements, because the web build is pure Scala.js (no npm/ESM bundler) and the project
 * keeps a minimal dependency graph. The SPA stays one main.js + this one stylesheet.
 *
 * LIGHT THEME ONLY for now (dark deferred, dfraile 2026-06-18). The color roles below
 * are the single source of truth; re-seeding the palette is a one-block edit. Dark mode,
 * when it lands, is a `[data-theme="dark"]` block overriding the same --md-sys-color-*
 * variables plus a toggle — see the placeholder near the end of this file.
 *
 * Class naming: `md-<block>` with `md-<block>--<modifier>` (BEM-ish). The Scala side
 * references these names through `web.styles.Css` constants so a typo is a compile error.
 *
 * M5-T01 defines the tokens + the app-shell classes (top app bar, nav drawer, main).
 * The reusable component classes (.md-button, .md-card, .md-dialog, .md-text-field, …)
 * are authored in M5-T02 alongside the shared-component migration.
