/* Pavia BPLO resident portal — design system.
 *
 * Who this is for: a small business owner in Pavia, on a phone, doing an
 * unfamiliar government task once a year. Every decision below serves being
 * understood by someone who is not sure they are doing it right.
 *
 * The palette is Pavia BPLO's own — the dark green and warm cream of the app
 * residents already use (BPLO/lib/utilities/global.dart) — not the municipal
 * seal's navy. The seal is the LGU's crest; the green is this service.
 *
 * ELEVATION IS DECLARED ONCE. A surface is either bordered or raised, never
 * both: a 1px border under a wide soft shadow is a smudge, not depth. Flat
 * bordered panels are the page; shadow is reserved for things that genuinely
 * float above it.
