/*
 * styles.css — VisaMatch AI design system
 *
 * A note on the stack. The PRD names TailwindCSS; this is a hand-written
 * stylesheet instead, for the reasons the same PRD gives for choosing vanilla
 * JS: performance, simplicity, fewer dependencies, zero cost. Tailwind here
 * would mean either a build step (contradicting "no framework") or the Play
 * CDN, which ships a ~400KB runtime compiler and would blow the <2s first-load
 * budget on its own. What follows is the same utility-plus-component model,
 * precompiled by hand: ~15KB, no build, no runtime.
 *
 * Design language: Linear / Vercel / Stripe — restrained palette, one accent,
 * real hierarchy from spacing and weight rather than colour.
