/**
 * Industry pack: HVAC.
 *
 * Two jobs, kept in one file on purpose:
 *   1) vertical token overrides (unlayered, so they win by cascade);
 *   2) the HVAC component layer: buttons, footer, cards, hero chrome.
 *
 * Layout contract enforced here (fixes the header/footer/content
 * misalignment at its root): there is exactly ONE page boundary.
 *   --ww-shell-width = max page width (1216px)
 *   --ww-gutter       = the page inset inside that boundary
 * Every full-bleed band (header, hero, footer) and every content shell
 * aligns to the same boundary minus the same gutter, so nothing can
 * drift left or right relative to anything else.
