/*
 * Styling for the /ui/ surface.
 *
 * GitHub's Primer is the visual reference, not a dependency. The values below
 * are Primer Primitives — its light colour scale, 4px spacing rhythm, type
 * scale and 6px radius — applied by hand to the handful of components this UI
 * actually uses.
 *
 * Vendoring @primer/css would ship ~400 KB of mostly-unused CSS to maintain,
 * and loading it from a CDN would make every page depend on a third party and
 * break the UI whenever that host is unreachable. Neither is worth it for six
 * pages. This file is embedded in the binary and served from memory.
