/* HiMint homepage prototype. Direction "The sentence is the layout" (tasteskill, seed 324154751, tone bold): the page
   reads as a run of short sentences, each with its proof beside it. Brand colours from docs/brand (Mint, Forest, Teal,
   Paper; the "-2" values are one tone step for fields). Type: Red Hat Display Black over Red Hat Text, chosen for its
   round bowls, which echo Mint's mark (handbook v1.2 §10; the two dealt faces clashed with the brand). */
