/*
 * /kai — Kaitago digital contact card. Brand Mark v1.0 / Homepage Design
 * Lock Phase 2 (30/08/2026). Mobile-first, one page, three actions.
 * Tap targets ≥44px per Identity Board §05 ("Vùng chạm tối thiểu 44px").
 * 3px radius on the card/buttons per Identity Board §07 (this website's
 * own convention). No shadows, no gradients, no pills — matches the rest
 * of the site.
