   The hero reuses .hero--home (background, dark mode and spacing are the homepage's own); everything below is
   prefixed .hl / .hlp and only exists on the lab page. Text colours are driven by variables set on #hero-lab by the
   lab menu (ink / card / size / palette / accent); the #hero-lab id is only here to win over the homepage's own
   hero text rules in every theme. Colours are rgba()/rgb()/tokens, no new hex. */
