/*
 * performance-card.css — the unified PerformanceCard widget (PERFORMANCE_CARD_CONTRACT.md §6,
 * COMPONENT_CATALOG.md § PerformanceCard). Every surface that renders a performance card
 * (Community carousels + expanded list, My Profile rows, My Recordings grid, Explorer / member
 * profile lists, musician dashboard tracks, the standalone performances window, Web feed) shares
 * this one sheet.
 *
 * Extracted from styles.css on 2026-09-03 (THEMES_CONTRACT §5.3 draft row "Unified performance
 * card") and re-laid-out as a fixed three-row grid so every card has the same form factor no
 * matter its type:
 *
 *   ┌──────────────────────────┐
 *   │ media   (16:9, fixed)    │  row 1 — thumbnail or placeholder, same height on every card
 *   ├──────────────────────────┤
 *   │ info    (fills the rest) │  row 2 — title · subtitle · details | badge column
 *   ├──────────────────────────┤
 *   │ actions (one neat row)   │  row 3 — pinned to the bottom, uniform control height
 *   └──────────────────────────┘
 *
 * Cards in one carousel row / grid row stretch to the tallest sibling (flex/grid `stretch`);
 * only the info row absorbs that extra height, so media tops and action bars line up across
 * solo, open-duet and full-duet cards alike. Nothing is truncated: titles and names wrap.
 *
 * Mirrored byte-for-byte to web/public/desktop/performance-card.css (TH-008 / registry id
 * `performance-card-css-th008`). Semantic tokens only (.claude/rules/ui-tokens.md); neutral
 * black/white scrims are the documented exception (tools/check-css-semantic-tokens.js).
