/*
 * Jim AI — public site.
 *
 * A dark, consumer-app landing aesthetic. Two readers have to be served at
 * once and they want different things: someone deciding whether to sign up,
 * and a carrier reviewer checking that specific required sentences are present.
 * The design leans marketing, but every compliance block (`.notice`) is given
 * its own high-contrast surface rather than being softened into the page —
 * required language that is hard to find is the one failure mode that matters.
 *
 * Committed to a single dark theme rather than following the system: the
 * policy pages and the landing page have to look like one product, and a
 * half-inherited light mode on a document page is where that falls apart.
