/* TAMIIIKKO/TAMIKO skin for the LernApp (Shifu).
 *
 * This file is a pure OVERLAY: it is loaded AFTER the inline <style> block in
 * index.html and wins by cascade order. The original inline stylesheet is not
 * touched — remove the corresponding <link> in index.html to disable this skin
 * entirely, or run `./revert.sh` to also restore the pre-Tamiko index.html.
 *
 * Design principles applied from the Tamiko system:
 *   - IBM Plex Sans as body font (Chinese fonts unchanged for CN characters)
 *   - Graphite neutrals: surface/ink tokens
 *   - Navy accent (#3a5c8a) — matches the launcher's --acc-lernapp
 *   - Keep correct/wrong colours: they are semantic state feedback, valid use
 *   - Keep XP gold: it's a game element, not chrome
 *   - Cleaner shadows without blue tint (Tamiko: achromatic)
 *
 * Deliberately NOT changed:
 *   - The pop/shake/pulse animations (kids app benefits from motion)
 *   - The Panda / mascot / celebratory bits
 *   - Chinese font stack (Ma Shan Zheng, Noto Sans SC, etc.)
