 * PAGE BLOCKS — hero, toolbar, grid, card, empty state

/* ============================================================================
 * PHASE 9 — SHARED PAGE BLOCKS
 * ----------------------------------------------------------------------------
 * The home page was rebuilt from a small set of blocks. Every other public
 * page needs the same ones, so they live here rather than in a page sheet:
 *
 *   .tx-page-hero  two-column page opening (copy left, facts right)
 *   .tx-bar        the toolbar that carries search, filters and a count
 *   .tx-grid       the browse grid
 *   .tx-card       one item in it
 *   .tx-state      empty / no-match
 *
 * Tokens only — no new colours, no new typeface.
