/*
 * mp-ui.css — Marketplace Prep shared COMPONENT layer (CANONICAL)  [ADR 0075]
 *
 * The "bones" half of the one-platform design system. mp-tokens.css supplies the
 * design language (color / type / spacing / radius); this file supplies the
 * components built from it — app shell, sidebar/nav, buttons, form fields, cards,
 * KPI/stat readouts, tables, pills/chips/badges, alerts, status LEDs — so every
 * surface stops re-rolling its own. Extracted and tokenized from the mature sets
 * in sites/ops/ops-shell.css (shell/nav/LED/picker), the Shipping Wallet inline
 * styles (KPI/table/pill vocabulary), and sites/portal/portal.css (buttons/fields).
 *
 * Load AFTER mp-tokens.css:
 *   <link rel="stylesheet" href="/mp-tokens.css">
 *   <link rel="stylesheet" href="/mp-ui.css">
 *
 * Shared-asset managed (shared-assets.json): edit ONLY this canonical file; the
 * per-surface copies are generated by sync-shared-assets.sh and drift-gated by
 * check-shared-assets.sh. Copies are added to the manifest AS EACH SURFACE MIGRATES.
 *
 * ── NAMESPACE ────────────────────────────────────────────────────────────────
 * Every class here is prefixed `mp-`. This is deliberate: each surface still has
 * its own unprefixed `.btn` / `.card` / `.panel` / `.alert` that mean different
 * things, so a surface can adopt these components ONE AT A TIME (swap `.btn` ->
 * `.mp-btn`, delete the local rule) with zero collision. Modifiers use BEM-ish
 * `--` suffixes (`.mp-btn--ghost`, `.mp-pill--bad`).
 *
 * ── THE TWO CONTEXTS (read before adding anything) ───────────────────────────
 * 1. CHASSIS (header + sidebar) is a DARK graphite bar in BOTH light and dark
 *    themes. Its internals therefore use the theme-INDEPENDENT on-brand tokens
 *    (--mp-on-brand, --mp-on-brand-muted, --mp-line-on-brand) and white-alpha
 *    literals for hover — both correct because the ground is ALWAYS dark. Never
 *    use --mp-fg (dark ink in light theme) on the chassis; it would vanish.
 * 2. CONTENT (main column: cards, tables, KPIs, forms) FLIPS with the theme. Its
 *    text uses --mp-fg / --mp-fg-muted, surfaces use --mp-bg-*, and hovers/tints
 *    use the theme-aware --mp-interactive-bg-hover (dark-alpha on light,
 *    white-alpha on dark). NEVER a raw rgba(255,255,255,.n) hover here — it is
 *    invisible on the light ground.
 *
 * ── READABILITY CONTRACT (owner requirement) ─────────────────────────────────
 * Body/secondary text uses --mp-fg / --mp-fg-muted (both AA in both themes).
 * --mp-fg-faint is ~3:1 — decorative/large/uppercase-label only, never body.
 * Green is a FILL (dark --mp-on-primary ink on it), or --mp-primary-dark as green
 * text on a light ground. Every accent pill pairs its accent text token with its
 * accent -bg token, both of which flip per theme, so contrast holds in both.
