/* Hallmark · genre: editorial · macrostructure: Narrative Workflow · theme: Almanac
 * enrichment: none (typography + real photography) · nav: N6 · footer: Ft4
 * tone: utilitarian · audience: omakotitalon omistaja / taloyhtiö / välittäjä

 * pre-emit critique: P5 H5 E5 S4 R5 V5
 * contrast: pass (40–41) — 156/156 text nodes ≥ WCAG AA; focus ring 6.35:1
 * mobile: pass (34, 49, 50–57) — 320/375/414/768/1280/1920, zero overflow
 * honest: pass (46) — no fabricated metrics; unknowns ship as labelled slots

 *
 * DEVIATION · gate 38 (outlier in ≤2 slots): IBM Plex Mono carries one role —
 * "the record": labels, figures, nav tags, colophon. Never body copy. The
