/* Hallmark · shape: Manifesto · genre: editorial · theme: custom (warm paper, one rust signal, Gambetta over Switzer) · redesign of the first build, content kept
 * hero: Settled, the claim set huge on paper · nav: edge-aligned, the wordmark and three links · footer: mast, the wordmark over the legal row · imagery: none, type and facts carry the page · signature: the studio's one claim, "We make apps people keep", set at display size on the first screen
 * axes: light/roman-serif/warm · posture: restrained · contrast: pass · fold: pass */
/* Hallmark · pre-emit critique: P4 H4 E4 S3 R5 V4 · weakest: S, the studio has no shipped apps or screenshots yet, so the page argues by its three working rules and a plain contact rather than a portfolio */
/* Hallmark · dismissed 58 · words were counted per screen after the cut; the hero is the headline, one twelve-word sentence and two actions */
