/* ==========================================================================
   design-swiss.css — Minimalism / Swiss Design language
   International Typographic Style: monochrome (black/white) with a
   single bold red accent, zero corner radius, thin 1px hairline
   borders instead of shadows for surface definition, huge restraint —
   no gloss, no glow, no texture. Deliberately the "quiet" option
   against the rest of the switcher's mostly maximalist/textured set.
   Scoped entirely under [data-design="swiss"] so it's inert otherwise
   — see includes/design_switcher.php and main.js's
   initDesignSwitcher() for the attribute mechanism.
