/* ============================================================
 * BANNA Overrides v7 — Surface Inference + Button Contract
 *
 * NEW APPROACH (after Rocky's button visibility bug):
 *
 * 1. SURFACE INFERENCE: detect inline dark bg → auto light descendant text
 *    No more guessing. Element with bg:#0A0A0A → children get bone text.
 *
 * 2. BUTTON CONTRACT: ALL buttons must have explicit bg+text pair via class
 *    .banna-btn-* explicit, .btn-primary/secondary mapped, no inline color.
 *
 * 3. NO CATCH-ALL FORCE-COLOR rules. Those broke buttons in v6.
 *
 * 4. Surfaces (only 3): dark #0A0A0A, light #FAFAF7, soft #F5F1E9
 *
 * 5. Body text rgba safety still active (catches faded-white bug).
