   Content source: ARC_Website_Design_2024_2.pdf, extracted, every string in its own order.
   Design direction: porsche.com. Devices borrowed, named where used:
     · a ghost identifier behind the hero, not a competing headline
     · numeral-first blocks: one huge figure, one small caption
     · hard ground cuts at section boundaries, never gradients
   Palette: David's cyan and yellow survive as sparing accents on neutral grounds. */
