/*
 * aptivus.io — the public site (docs/ENVIRONMENTS.md). Plain HTML and this one
 * stylesheet, no build and no script, so the strict CSP in vercel.json holds.
 *
 * The values are the app's (packages/ui/src/tokens.css): warm-white light
 * neutrals at 6400 K (D-064), an ink accent, colour only for status, Geist.
 * The home page is one narrow column of quiet type; its only drawing is done
 * with a pen — the mark sketching its own outline before it inks in, and a
 * scribbled underline — so the motion is two lines being drawn, nothing more.
