/*
 * Quark 2 — Cal.com-inspired design system atop PicoCSS
 * ----------------------------------------------------
 * Principles (per DESIGN.md):
 *  - Monochrome palette; color is foreign.
 *  - Cal Sans for display, Inter for body.
 *  - Shadow-first depth: ring + soft + contact.
 *  - Generous whitespace; 80-96px between sections.
