/* ──────────────────────────────────────────────────────────────────────
   Virtuzone — concept site. Original design, not a recreation.
   Palette: brand red/orange accents on calm ink+navy+paper system.
   Justified by: logo SVG (#FE294D + #FD6611), corporate-trust sector
   expectations, lead-gen conversion contrast, regional cue (UAE / GCC
   editorial design favours saturated reds on quiet neutrals).
   Palette differentiator: this design uses a *red→orange diagonal*
   only on primary action surfaces, and otherwise stays near-monochrome
   ink/paper — distinct from the current site's heavier red usage.
