/*
 * Placement: <app root>/public/assets/app.css
 *
 * Mobile-first. Designed against a 380px viewport and one-handed use:
 * primary navigation sits in a bottom bar within thumb reach, tap targets
 * are 44px minimum, and nothing important lives in a top corner.
 *
 * Palette follows the console direction already in use on the P389 site,
 * so the two properties look like one operation: white ground, petrol
 * accent, Plex-style mono for every figure. No web fonts are loaded —
 * there is no CDN dependency anywhere in this application — so the mono
 * stack falls back to whatever the device has.
