/* Spin & Paint — shared stylesheet.
 *
 * Palette lifted from src/theme.ts (CHROMA): flat #161616 ground, #1D1D1D
 * panels, #F3F3F3 ink, forest-green accent #0F810F.
 *
 * One constraint carried over from the app: --accent is FILL ONLY. On #161616
 * it measures 3.6:1, under the 4.5:1 body text needs. Accent-colored TEXT uses
 * --accent-ink (#5BD46F, ~9:1). Never swap them.
 *
 * No webfonts and no JS: the FAQ is <details>, the nav is a plain list. The
 * whole page is two requests plus images, which is most of the Core Web Vitals
 * budget won before a single byte of layout.
