/* Buttons — design system
   ────────────────────────
   .btn         = base outlined (transparent bg, neutral border) — secondary actions
   .btn-primary = solid amber — the ONE main action per toolbar
   .btn-danger  = solid red — destructive (delete, reset) only
   .btn-toggle  = outlined + amber-tinted when [aria-pressed="true"] — view/mode toggles
   .btn-icon    = 32×32 square modifier for icon-only buttons
   .btn-sm      = small variant for inline/row actions
   .btn-success / .btn-info / .btn-warning kept for backward compat — avoid in new code,
   reserve those colours for badges/dots where they actually carry meaning. */
