/* Hallmark · pre-emit critique: P4 H5 E4 S4 R4 V5
 * Hallmark · genre: atmospheric (playful voice) · macrostructure: Marquee Hero · H1 Marquee knobs: size=xl, alignment=left-bias, underlay=rule-below, no eyebrow
 * theme: custom · vibe: "playful precision, after-dark glow, solid and moving" · paper: oklch(13% 0.022 285) · accent: oklch(74% 0.16 55)
 * display: Bricolage Grotesque · body: Geist · outlier: Geist Mono (footer meta only) · axes: dark / display-heavy / warm
 * enrichment: E7-adjacent abstract background — two radial blooms (Tier A CSS art), scroll-driven drift at user request, static under reduced-motion and below 40rem
 * nav: N5 Floating pill (width=content, backdrop=blur+saturate, anchor=top-centred) · footer: Ft5 Statement (38ch, wordmark under, hairline)
 * sections: S2 hanging heads · F4 step sequence (1.0 numbering, horizontal, line connector) · F3 spec sheet (3 col, every-row rules) · C2 inline form · C3 typographic links
 * modes: dark default by system preference, light variant, manual toggle persisted · studied: no · context: user-provided · v1.1.0
 * slop test: 58/58 · contrast: pass (40–41) · nav/footer/hero: pass (42–45) · honest: pass (46, placeholders labelled) · chrome: pass (47) · tokens: pass (48) · responsive: pass (49) · icons: pass (30) · mobile: pass (34, 49, 50–57)
 * noted deviation: gate 29 says blooms are static; scroll-driven drift is an explicit user request, transform-only, off under reduced-motion and below 40rem
