 * hero: split, the van on the right · nav: edge-aligned, the logo plate and one call action · footer: contact mast over the company line · imagery: photographs (the client's own, from Facebook) · signature: the black van with the yellow stripe, and the phone number set like it is on the van · ink: paper, accent swapped to SMK yellow

/* Hallmark · pre-emit critique: P4 H4 E4 S5 R4 V3 · weakest: V, one deal so far; varied by moving the photographs into a pinned scroll instead of a grid */
/* Hallmark · waive 22 · ink, plate and greys at zero chroma · the SMK van and logo are printed in plain black and white with one yellow stripe */
/* Hallmark · dismissed F4 · the yellow fill only appears in the phone call bar, which replaces the header button below 40rem */
