/* NSFWBench theme v2: tokens and components for every page. Page layouts live in site.css (production)
   and explore.css (the /explore/ prototypes).
   Direction: research leaderboard. Flat surfaces, 1px borders, monochrome chrome, one restrained teal
   accent for selection, focus and data. Sentence-case labels, one heading per block. Dark by default,
   light via the header toggle. */
