 * Theme — FCI Brand
 *
 * Aligned with the Food Co-op Initiative brand guidelines (12.2022).
 * Primary palette: Eggplant (#801d7f), Spring Pea (#96bc33), Squash
 * (#c9ad2d). Secondary neutrals: FCI Dark Gray (#4b5657), FCI Beige
 * (#D2C9B0), Seed Grant Green (#679038). Type: Open Sans (FCI's free
 * substitute for Museo Sans, per the guidelines).
 *
 * Semantic token names from the previous theme are preserved so existing
 * component class names continue to apply:
 *   - leaf-*  → Spring Pea / Seed Grant green family
 *   - clay-*  → Eggplant purple family (brand primary accent)
 *   - squash-*→ FCI yellow accent (new)
 *   - paper/ink → clean neutrals tuned to brand gray
 * ─────────────────────────────────────────────────────────────────────── */
