   Ported 1:1 from the design source "Product Pages/ARTILUX PQC_0708.html"
   (tp-* system: spec strip, challenge/solution split, fully-integrated
   feature grid, split CTA). Loaded only on this page via $d['css'][].
   The original SVG light-art hero (tpl/products_odyssey.html) is kept; everything below
   the hero is this 0708 content, with its styling preserved verbatim.
   Tokens (--c-*, --font-*) come from css/artilux-c.css.
