- replace the ~100-option avatar <select>s in Add Relic / Add Light Cone with a searchable picker modal (keep-in-inventory card + avatar cards with element/path/level)
- warn when the chosen character already wears a relic in that slot or a light cone
- click+Confirm or double-click applies; Esc closes only the picker; search autofocused
- localize all new strings (th/en, other locales fall back to en) and refresh chips/picker on language change
- add AGENTS.md with localization and cache-busting rules
- bump app.js v3.20, styles.css v2.29, i18n.js v2.17 and align all i18n imports
Layout: card now fills its container (3/2/1 columns) with no horizontal scrollbar.
i18n: every modal/showcase/console string follows the selected language, named fallbacks for th/en plus English fallback for other locales, localized character names and light-cone passive text.
Showcase stats use the official in-game property icons (same set as the overview tab) instead of emoji, including the element DMG icon.
Export: fixed 1200px clone with poster metrics, cover-cropped splash art (html2canvas ignores object-fit), transparent background so the rounded corners have no dark wedges, and a two-pass measurement inside the capture iframe so the PNG is never cropped.
