/*
 * Layout: the airy structure of the app (D6 revision; originally "direction A"). Layers on tokens.css + components.css.
 * The skin (skin.css, decision 56 = B) sits on top of it.
 * Idea: the list shows only what decides a tap (score, title, category, time); everything else lives in the card,
 * and the card itself opens progressively (hero → one action → collapsible sections).
