/* ============================================================================
   Common action buttons — GstActionButton / GstActionBar
   (MainApp.Razor.SharedUILib/Shared/GstActionButtons). #region Himanshu (09-Oct-2026)

   One button, eight looks. The LOOK is chosen by the user (Appearance → Other themes → Action
   buttons) and arrives as body[data-actbtn="tile|outline|soft|raised|pill|stacked"]; the ICON
   treatment arrives as body[data-actico="colorful|mono|none"]. A GstActionBar may force its own
   look with the same data-actbtn attribute (showcase previews).

   HOW THE VARIABLES WORK — read before editing. A custom property is resolved on the element it
   is declared on. The looks are declared on the SCOPE (body / .spq-abar), where no button tone
   exists, so a look may only set TONE-FREE values: percentages, sizes, keywords, neutral colours.
   The button (.spq-ab), which knows its tone, mixes those percentages with its tone colour:
       color = color-mix(tone-text  <fg-tone>%,  fg-base)
   Never write var(--ab-tone…) inside a look block — it resolves to nothing and paints black.

   TONE (neutral / primary / portal / success / danger / warning / info) is fixed per action and
   never changes with the look: red is always destructive, green always means GST-portal traffic
   (label green, caption / timestamp dark green in every look — see section 6).
