/*
 * Almira Tiket Event — Design System
 * ----------------------------------
 * Hand-authored implementation of `styling.md` (Blue & Clean UI).
 *
 * Why plain CSS instead of the repo's Tailwind/Vite pipeline:
 * `styling.md` is authored as raw CSS tokens and component rules, and the
 * Node toolchain is not installed in this environment, so Vite cannot
 * produce a build. This file is served directly from `public/` so the UI
 * renders without a build step. Migrating these tokens into Tailwind v4
 * `@theme` is a tracked follow-up, not an abandoned decision.
 *
 * Token values are copied verbatim from `styling.md`. Do not invent new
 * colors, radii, or spacing values here — extend `styling.md` first.
