/* Hallmark · pre-emit critique: P5 H5 E4 S5 R5 V4
 * Hallmark · genre: editorial · macrostructure: Split Studio · theme: Almanac
 * tone: utilitarian · anchor hue: warm 42 (signal orange on birch paper)
 * nav: N12 banner + retract (status fill, no dismiss) · footer: Ft4 dense colophon
 * hero: H2 split diptych 7/5 · heads: S2 hanging · features: F3 spec sheet + F4 step sequence
 * cta: C1 outlined chip · enrichment: none (real photography, no illustration)
 * motion: nav retract · button press · focus ring (no scroll reveals — editorial is still)
 * slop: pass (42–45) · contrast: pass (40–41) · mobile: pass (34, 49–57)
 * gate 38 note: the mono outlier carries ONE role — machine data and micro-labels
 * (dimensions, phone, step numbers, colophon). It never sets prose. Keep it that way.
