rustio-admin 0.21.1

/* ============================================================
 * rustio-admin / pages / dashboard
 *
 * Operator-facing "Site administration" home. Five vertical
 * regions:
 *
 *   1. Greeting header  — friendly hello + page title + env badge.
 *   2. Stats strip      — four pastel tiles using semantic `-bg`
 *                         tokens (info / success / warning / accent).
 *   3. Model grid       — one flat CSS-grid of every project model.
 *                         Tiles cycle through four accent palettes
 *                         via `:nth-child` for visual rhythm; the
 *                         grid auto-fills to 3-4 columns at desktop
 *                         width and collapses cleanly on narrow.
 *   4. Activity feed +  — two-column split below the grid. Recent
 *      Framework tools     audit rows on the left (~2/3); a card
 *                          of framework-tool links on the right
 *                          (~1/3). Stacks on narrow viewports.
 *   5. (recent activity in empty-state form when no audit rows.)
 *
 * Doctrine: light + restrained. Pastel tints come from the
 * framework's already-calibrated semantic-color tokens; the
 * cycle adds visual variety without departing from the palette.
 * ============================================================ */

 * but the result read as "festive" rather than "professional".
 * The new tile is one consistent white surface with a 3-px
 * top accent bar — Stripe Dashboard / Linear / Vercel
 * convention. Color is reserved for SEMANTIC meaning
 * (success/warning) rather than per-tile decoration.
 *
 * Variants (`.rio-stat--info` etc.) are preserved as kept
 * selectors so existing markup keeps working; they only flip
 * the top accent bar's color now, not the whole tile fill.
