   CPUWAX theme v1 — loaded AFTER core /assets/css/site.css.
   Goal: a precise "PC-builder tech" look, clearly NOT the siblings.
   KitzYou        = warm brown, rounded, centered header.
   TaladAutoCar   = orange on ink, dark hero, dark catbar.
   TaladHouse     = olive on warm beige, light everything.
   ArsomSolarCell = sky blue + amber, bright hero.
   CPUWAX         = deep navy + electric cyan, circuit-line hero,
                    cool gray-blue page bg, Chakra Petch headings,
                    crisp 8-10px corners, cyan CTAs on navy.
   Palette: #0AA6C9 cyan · #086F87 cyan-ink · #0B1220 navy · #F3F6FB bg
            #101828 ink · #7C5CFF violet (badges/glow only, never CTA)
