+-- 033: Phase 5 — shop catalogue expansion
+--
+-- Triples the shop's selection (10 → 30 items) so coins finally have
+-- something interesting to buy. Adds:
+--   • 12 new frames spanning price tiers 200-1200, palette covering
+--     warm/cool/multi-color/animated/event ranges
+--   • 9 new titles in 150-2000 coin range (some prestige-only)
+--   • 1 new theme (warm paper) using the existing theme slug system
+--
+-- Effects are intentionally NOT extended here — the front-end
+-- _applyEffect() in js/api.js only supports pulse/sparkle/snow today,
+-- and adding new effect kinds belongs in a follow-up that updates the
+-- renderer. Frame previews and title pills already render properly
+-- thanks to the Phase 4 shop UI changes (profile.html).
+--
+-- Re-runnable (INSERT OR IGNORE — `name` is informational; the dedup
+-- happens because the (name, type) pair would already be in shop_items
+-- after the first run, but to be safe we re-check by name+type below).
+-- ═══════════════════════════════════════════════════════════════
+
+-- Helper pattern: INSERT only if no row with same name+type exists.
+-- We can't use INSERT OR IGNORE without a UNIQUE index, so do it via
+-- WHERE NOT EXISTS for each row.
