/* ============================================================
   AVEA — design A, Night / Day (D-2026-10-24-01).
   Postal.id's layout — fixed header with a centre capsule, menu
   panel, pill buttons, large rounded panels, a label column on
   the left — in AVEA's own colours, Hanken Grotesk and wordmark.
   From the home page of the design canvas, "AVEA Design
   Explorations". Night is the default; <html data-theme="day">
   is Day. Every page uses it: the inner pages (A-022) are the
   home page's blocks plus a few of their own, at the end.
