/* ============================================================
   buttons.css v2: Byteland house button system, HYBRID edition.
   Approved by Sleek on store compare.html v3 (Sept 2026).

   LOAD THIS FILE LAST on every property (after its own css).
   Same selectors, later cascade: it overrides the gamey look
   without touching each property's own stylesheet.

   Ethos: premium with a pulse. Sparse ANIMATED gradients.
   Sentence case (kills uppercase + wide letterspacing), pill
   shape, same-hue gradient pan on primaries, sheen sweep on
   hover, calm glass ghosts with a gradient hairline on hover.
   No rainbow, no neon halo, no scale pop.
