/* fof.lol — shared look of the single-page *Bench tools (SpeedBench, WhereBench, KeyBench, DropBench, MeetBench, PrivacyBench, PhotoBench, TypeBench, ToolBench, QRBench, PDFBench, PassBench, TimeBench, TuneBench, DrawBench, RandomBench, ScanBench, TextBench, PowerBench, ColorBench, DevBench).
   A tool sets its colour with two tokens and keeps only its own components inline:
     :root { --accent: var(--pumpkin); --accent-ui: var(--melon); }
   --accent tints the product name and the shared/saved banner; --accent-ui is the focus ring and primary-button hover. */
