/*
 * Product page variation 4, "Steel and Yellow" (parts/product-sheet/v4/, round 4, ?pv=4 off
 * production). Loaded after home-b.css and product-sheet.css; every rule is scoped to
 * body.hdc-pdp--v4.
 *
 * A calm engineered page with a second color: deep steel blue for heading accents, icons,
 * links and the quote button. Safety yellow stays the Call fill and the stars. Soft 10 px
 * corners, 1 px borders on white or on a faint cool steel tint, no shadows, no pills. The
 * two tone icons (icons.php) fill their tint shapes with the light steel tint and draw the
 * line work in steel. Bands alternate white and the faint tint, never warm.
 * Breakpoints 40rem, 48rem, 64rem, 80rem. Layout rules are not nested.
