/* Essence of Islam viewer chrome — the top bar, the contents drawer (right) and the text-size
   control. Injected into every book at request time (src/lib/site.ts) together with viewer.js; the
   master store in the collection project never references it (docs/viewer.md).
   Chrome sizes are px on purpose: A− / A+ change the ROOT font size so the em-based kit rules
   scale, and the bar and drawer must not grow with the text. */
