   WARM-UP · 热身 · Sentence-builder teacher tool
   Teacher host page has the full library + sentence stage. Player phone
   has a read-only mirror of the current sentence. Every word card carries
   its category color (--cat-color) so pinyin + Spanish translation share
   colors and reveal sentence structure at a glance.

 * 📜 MIS ORACIONES — full-screen sentence library
 *   Fernando 2026-06-04: "This is the main language essence. Make it
 *   bigger, full screen, beautiful, scale perfectly."
 *
 *   Layout decisions:
 *   - .wu-history-modal is now a full-viewport sheet, not a modal.
 *     Background fades over the page; the sheet itself is opaque so
 *     the kid focuses entirely on their collection.
 *   - .wu-history-sheet is the scrollable inner column. Max-width
 *     1100px so it doesn't sprawl on 4K monitors but goes edge-to-edge
 *     on phones.
 *   - Sticky hero header with a big ← back chip + title + counts.
 *   - Tabs are sticky right under the hero so flipping between
 *     "✍️ Mías" and "📤 De la maestra" doesn't lose your place.
 *   - Cards are a responsive grid: 1 col on phone, 2 on tablet,
 *     3 on desktop wide. Each card shows date, words (with hanzi +
 *     pinyin + icon stacked), 🔊 Escuchar button, 🗑 delete.
