/* Hallmark · pre-emit critique: P5 H5 E5 S4 R5 V5
 * Hallmark · genre: atmospheric · theme: Midnight · nav: N5 floating pill · footer: Ft5 statement
 * Hallmark · macrostructure: Marquee Hero (home) · Index-First (portal) · Long Document (post)
 * Hallmark · tone: atmospheric · audience: prospective clients + employers · use: explore the work
 * Hallmark · anchor hue: warm 45–58 · enrichment: none (typography + two fixed blooms)
 * Hallmark · type: Geist (display + body) + Geist Mono (outlier role: machine-set text —
 *            wordmark, metadata, hostnames, index labels, code). 2 families.
 * Hallmark · contrast: pass (40–41) · honest: pass (46) · chrome: pass (47)
 * Hallmark · tokens: pass (48) · responsive: pass (49) · icons: pass (30)
 * Hallmark · mobile: pass (34, 49, 50–57) · nav: N5 · footer: Ft5 · slop: pass (42–45)
 * Note on 40: hairline rules (--color-rule / --color-rule-soft) sit below 3:1. They are
 * decorative row separators, not control boundaries — every row and card is identified by
 * its own text and surface fill, so WCAG 1.4.11 does not bind. All text pairs clear 4.5:1.
