/*
 * cubesite.css — the shared stylesheet for cubicecho project sites.
 *
 * Source of truth: github.com/cubicecho/cubesite → theme/cubesite.css.
 * This file is VENDORED into each project site (site/src/css/cubesite.css), so
 * edit it there only to find out what you want changed here, then change it
 * here and re-sync with `node scripts/scaffold.mjs <repo> --theme`.
 *
 * It expects the markup in cubesite's template/src/_includes/base.njk. Project
 * rules go in a second stylesheet (site.css) loaded after this one, never in
 * here — a project-shaped rule in the shared file is how the shared file stops
 * being shareable.
 */

/*
 * The palette is cubeui's — tokens/palette.mjs there is the source, and these
 * are its default light and dark values under its names, as dist/tokens.web.css
 * emits them. A token is named for what the colour means, and nothing is a
 * quieter copy of another: muted text is `foreground` at 60%, a border is
 * `foreground` at 10%, written as a color-mix() where cubeui writes
 * `text-foreground/60`. Change a value there first, then here.
 *
 * Dark follows the system. cubeui's web build keys it off `.dark` on <html>
 * because an app has a toggle; a static page has nothing to set the class.
