/* Measurement Archive — Broadsheet design system.
 *
 * Newsprint set for the web: near-black Source Serif 4 on paper white, with two
 * process accents (cyan + magenta) used small and deliberately. Page structure
 * uses no boxes and no dividers between sections — hierarchy comes from the serif
 * scale and negative space. The one place rules print is front-page furniture:
 * the thick-thin head pair around the dateline rail.
 *
 * Tokens and components ported from the Broadsheet system (design/). The font is
 * loaded by base.html, not here, so the CSP's font-src stays satisfied.
