   VHS Title Generator — "Operate the deck"
   The page is a CRT TV + VCR. Interface voice = VCR OSD Mono (the camcorder
   on-screen-display font). Palette + accents come from real VCR hardware and a
   vintage broadcast title look: warm near-black, segment-display amber, teal
   + orange. One signature: the blinking 12:00 VCR clock and the OSD menu.
