/* Survey Insight Skills — landing page styles.
   Editorial-technical: grotesque type, hairline rules, monochrome throughout,
   with one lime signal colour (--signal) reserved for "act here": the primary
   CTA, the active language segment, the logo tile, the pull-quote bar and link
   underlines on hover. No amber, no red — reliability warnings are rendered
   neutrally (surface, --text left border, ⚠ glyph, bold label) so they read as
   warnings without relying on colour. See CLAUDE.md for the token table. */
