/* =============================================================================
   SPECTRAL41 — shared button system (Prime + $SPECTRAL)

   One "terminal" identity for every clickable action across /prime and
   /spectral: mono, uppercase, single radius (--r-sm), shared hover/active.

   Relies on tokens defined in each page's :root — --mono, --text, --text-2,
   --hairline, --hairline-strong, --accent, --accent-dim, --panel, --r-sm,
   --ease, --shadow-1, --shadow-pop.

   Loaded via <link> BEFORE each page's inline <style>, so page-specific
   geometry (widths, the acquire pill internals, frosted masthead, etc.) can
   still override these without !important.

   Roles:
     .btn (+ --primary / --accent) ... text action buttons (one family)
     .iconbtn (+ --sm) .............. square icon buttons
   Pills / segments (.facet, .mod__tag / #standingTag, .seg__btn) are a
   deliberately SEPARATE role, defined per page — they are NOT .btn.
