/* ============================================================
   Reaction ERP — the UI library's own controls (js/components/ui/).
   ------------------------------------------------------------
   Only .ui-* selectors, only tokens from theme.css. Everything a control
   borrows from the app (.pill, .alert, .progress, .tabs, .form-section,
   .tl-item, .pcard-*, .al-pager, .gt-*, .sdd-*, .chip, .form-file-strip)
   is painted by theme.css / layout.css and left alone here, so skin.css
   (which keys on those class names) and responsive.css still apply.

   Two house rules run through every control:
   - the Thai line-box rule (theme.css:181-191): a control states its
     line-height and min-height, so it is the same height in both languages;
   - the z-index scale (theme.css:95-104): anything that floats takes its
     layer from a --z-* token, never a number of its own.
