/**
 * Narrow layout: no cards.
 *
 * On a phone the card look costs three nested paddings (main → section →
 * card) before any text, and one card per row wastes the whole viewport.
 * Here every panel is flat: full-bleed hairlines, exactly one level of
 * horizontal padding, and label/value on a single line. Status that the
 * card border used to carry is moved into the value colour.
 *
 * Loaded only for the narrow layout, after app.css.
