/* YKO — homepage. Instrument Grade tokens plus the four action colors added 8 Oct 2026
   (.claude/skills/yko-design/SKILL.md). Self-contained: the homepage loads this file
   and not yko.css, because yko.css still carries the Bright Signal palette.

   Colour rules, as written in the skill:
   --signal   primary action buttons and the 56x6 bar above section headings. Ink text on it.
   --headline one key phrase per heading; text 24px or larger only.
   --confirm  buttons inside product samples, white text.
   --sky      the headline phrase on the ink band only.
   --cut      the gap, once per screen. On this page: the supplier response chart.
   No green. No gradient except the 45 degree hatch on the gap. No icons. */
