/* Brinescale (opencure.net) v1.1.0: "the kitchen scale". Redesigned after the 2026-10-18 brand review (TB-1): cool enamel and
   brushed steel, a graphite instrument body, a reflective LCD in seven-segment digits, and the pink of Cure #1 as the one
   accent. Wide grotesque display type, no serif, no italics, no cream, no pills, no torn or perforated edges.
   Fonts self-hosted (SIL OFL 1.1): Krona One (display), Kantumruy Pro (text), Google Sans Code (figures), DSEG7 Classic (LCD). */
