   English Hub — student site themes (Jamshid, 2026-10-26)

   Two themes, one design: "Kunduzi" (Pearl, day) and "Kechasi" (Midnight
   Gold, night). Loaded only by the student site (index.html), after
   styles.css, so the teacher panel and the parents' page are untouched.

   The theme is a data-theme attribute on <html>, set before the page draws
   by theme-boot.js: the student's own choice, or the phone's setting.
   Everything below works through the tokens styles.css already uses, so a
   component that reads var(--surface) / var(--ink) follows the theme by
   itself; only the few places that need a different shape are restyled.
