/* ===========================================================================
   The Study: shared styles.

   PROVISIONAL design. No logo, palette or mockup has been approved yet, so
   this is a plain, readable starting point: warm paper background, white
   cards, a text wordmark, one deep blue accent, a serif for headings and
   (later) passages, system fonts only. Every colour and size lives in :root
   below so the look can be replaced in one place once a design is chosen.

   Layout lessons carried over from Da Hangout and Blend (read-only
   references): overflow-x: clip rather than hidden (iOS scrolling), 16px
   form text (no iOS zoom on focus), safe-area insets, flex children that
   never shrink to zero, readable form text, and keyboard focus kept clear
   of the pinned phone tab bar.
