/* NutriZaika pocket calculator (brief of 10 Nov 2026): one device in the middle of the page, at most 400 px wide.
   Light: brushed aluminium with white keys; dark mode (assets/dark.css) swaps the --pc-* colours for graphite.
   Keys have min-heights, never fixed heights, so 200% text makes them taller instead of cutting words. */
