   Palette : bone / espresso / marigold / deep teal, with a warm "2am mode"
   Type    : Iowan–Palatino serif for reading, system sans for UI and data
   Layout  : 1280px shell, two-column with a sticky rail
   Perf    : zero webfont requests — LCP gates ad RPM, so fonts cost nothing.
             All ad slots carry fixed heights so CLS stays at 0.
