/* Changelog timeline — 2026-08-24, implementing the owner's Claude Design
   draft `PDM Changelog Page.dc.html` inside the site layout. Colours map to
   the site tokens so the light theme keeps working; the draft's fixed hex
   accents (blue/cyan/green) become primary/accent/accent2. All rules are
   scoped .cl-*. */
