/* ---------------------------------------------------------------------------
 * Front page — section 6 "Half a million products. No timeouts." (dark band).
 *
 * Merged into main.css at the end of the pass.
 *
 * What the reviews found, and what changed here:
 *  · The band was a 1009px full-viewport slab carrying four paragraphs and one
 *    192px card. The card sat centred in a 520px column with ~164px of void
 *    above and below it. The two-column split is gone: head → full-width
 *    console → a four-across row of iconographed points, on --compact padding.
 *  · The 63-tick meter was a `repeat(auto-fill, minmax(10px,1fr))` grid, so it
 *    wrapped to two rows at 768 and three (with an empty third) at 360. It is
 *    now one nowrap flex row of `flex:1 1 0; min-width:0` ticks that compress
 *    to hairlines instead of wrapping.
 *  · The band had no iconography. Four conceptual line icons now sit on the
 *    points, one stroke weight, currentColor.
 *
 * Only tokens from main.css are used — no new shadow recipes, no new colours.
