Thin 36px strip in the topstrip grid-area: left = MONITORING THE SITUATION
label + about-trigger icon, center = HH:MM:SS UTC mono clock with tabular-nums
ticking once per second, right = settings gear (auth) or user (anonymous)
that navigates via ROUTES.{SETTINGS,LOGIN}. About icon dispatches openAbout
on the ui store; the modal itself is Task 23.
Pure monochrome — title --fg-2 letter-spaced uppercase --type-label, clock
--fg-2 mono, icons --fg-3 with --fg-1 hover color shift (no transition,
no scale, no rounded surface). Reads tmux-status-line, not SaaS app header.
focus-visible outline 1px --fg-2 for keyboard a11y. Dashboard.tsx renders
<TopStrip /> as a direct child of .root so it auto-places into the
topstrip named area.
Plan 5 Task 8 Design QA: strip height, label tier, mono tabular clock,
zero rounding, tmux feel — all verified.
