/* ==========================================================================
   P3 Account — Midnight Editorial, Configure/Inspect surface.

   Near-black paper, warm-white ink, restrained P3 cyan, twelve-column ledger,
   one-pixel rules. The account page is a place to configure and inspect, not
   a marketing landing page: the title stays a heading, sections are separated
   by rules instead of repeated glowing cards, and every control keeps a real
   44px floor. Tokens and rules are documented in DESIGN.md and
   docs/p3-midnight-editorial-guideline.md.
