/* Karvo - static marketing site v2 (2026-07-12), v5 additions (2026-11) at the end.
   Evidence-driven rebuild: see karvo-os/research/2026-07-12-design-conversion-research.md
   Budget rules: no JS, no external requests, one self-hosted font, total weight ≤300KB.
   v2.1 brand pass: palette sampled from karvo_logo.png - violet #6448dc (K stroke),
   blue #2a63c9 (gradient blue, darkened for 4.5:1 on white), navy #151c38 (wordmark),
   light violet #9a7dff → sky #58a6f8 for decorative gradients. Gold #f4b26e survives
   only as the demo-code highlight on dark cards. WhatsApp green is functional only
   (wa buttons, live dot, the WhatsApp phone mock). */
