/* JayBoard shared widget primitives — built on the tokens in theme.css. Loaded by both pages
   (index.html + board.html) after theme.css and before the page-specific stylesheet, so page CSS can
   still override where it must. One definition each for buttons, fields, menus, chips, and segmented
   controls, so a widget looks the same on the gallery and the board.

   Conventions: BEM-ish — .block, .block--variant (modifier), .block__part. */
