/* ==========================================================================
   HINDI READING LAB — styles
   --------------------------------------------------------------------------
   Two rules drive everything here:

   1. THE DEVANAGARI IS THE BIGGEST THING ON THE SCREEN, always. She is
      decoding shapes she does not yet know; 18px will not do. Letters are
      set in Tiro Devanagari Hindi, which has the clear, textbook-shaped
      counters a learner needs — not a display face.
   2. ROMANISATION IS NEVER SHOWN BY DEFAULT. It sits behind a button. If
      "kaa" is on screen next to का she will read the roman every time and
      learn nothing, which is exactly what happened on the tablet before.

   Tablet first: 44px minimum targets, no hover-only affordances, and the
   tracing canvas takes pointer events so a finger works.
