/* Saturn viewer — Datasheet Annual aesthetic.
 *
 * Palette: warm bone paper, near-black ink, single signal red.
 * Type system: Fraunces variable serif for display + prose,
 *              IBM Plex Mono for tabular data.
 * Grid: 12-column, 8px baseline, generous gutters.
 * Rules: 1px hairlines instead of heavy dividers; no alternating row shading.
 *
 * Load order: this file is the ONLY stylesheet. No component CSS. No utility
 * framework. Readability beats factoring here.
 */
