   developers.docly.net — site theme (facelift, October 2026)
   Loaded after bootstrap.min.css; replaces theme.css, custom.css and search.css.
   Brand blue #187bb0 kept. Light and dark via the tokens below (theme-init.js sets
   data-theme before first paint). Legacy template classes (docs-wrapper, docs-article,
   section-heading, alert-*, table) are styled here too, so content renders unchanged.
