/* ARC Cloud — site styles
   Brand DNA: rounded page frame on a gray ground, floating white navigation,
   light heroes with rendered satin artwork (assets/art, src/gen_art.py), one softly tinted band per page,
   white and silver neutrals with every accent drawn from the ARC logo hues (no black or green blocks) reserved for interaction, Inter Display + Geist Mono,
   white buttons with a dark pixel-arrow tile, numbered product rows, rounded hardware cards.
   Fonts are loaded from fonts.css (embedded) so pages also render when opened from disk. */
