/**
 * AIContestList — Search (/search/). Editorial Light with one Immersive Dark band for
 * prompt results (design-system §51). Tokens only.
 *
 * One idea carries the page: the visitor's words are the headline. The query is set in
 * Instrument Serif italic at display size, ink running into Iris; everything else is the
 * site's quiet editorial grammar — column lines, a whisper of light, hairline rules,
 * numbered chapters. The field is a command bar: one generous target, the query kept in
 * place, a gradient edge on focus.
 *
 * Breakpoints: 600 · 900 · 1024.
