/*
 * components.css — presentation for the two surfaces the ENGINE emits on every tenant:
 * the newsletter signup band and /archive.html.
 *
 * Why it is not in a tenant's site.css (2026-09-18): site.css is written per tenant by the
 * generator, which lives in another repo. Anything the engine emits unconditionally must carry its
 * own styling, or the first tenant built by an older generator ships an unstyled band and an
 * unstyled archive and nobody finds out until an owner looks at it.
 *
 * Every value here resolves through the palette and type custom properties in brand.css, so these
 * components inherit the tenant's identity exactly like the rest of the site. No literal colours,
 * no web fonts, no url() references.
