/*
 * Lodestar — lodestar.nookpages.com. One stylesheet for every page: no web fonts, scripts or third-party files.
 * Colours come from Lodestar's theme (packages/tokens from app.manifest.ts: sapphire #3558B2, brass #C8A15A, tinted
 * neutrals, the night-blue dark mode) and from the icon (assets/icon.png: its night-blue field, #1C2851 to #121D3E,
 * and its brass star, #D9B66E). Text pairs meet WCAG AA (4.5:1 or more) in both modes. Brass is never text on a light
 * background (2.3:1 on it): there it's shapes only, and words in brass use the darker #77560A. Type is the system's own
 * (SF Pro on Apple devices), as in the app: no serif.
