/* ================================================================
   SeeThru — "LED, Explained" guided spec-builder  (stx-led-explained)
   Ported from the design-system page assets/led-explained.css.
   Dark · editorial · monochrome. Accent = white. Selection = green.

   EVERYTHING is scoped under the suite root `.stx-le` so it out-specifies
   Rey's global element/attribute rules (e.g. button[type=button] = (0,1,1))
   without a single !important — see the rey-button-collision rule.
   The design tokens it relies on are inlined onto `.stx-le` (NOT :root) so
   they never leak into the rest of the Rey-themed page.
