/* Extra widgets for tool pages on the shared layout (assets/layout/layout.css tokens), Bootstrap-free.
   Added with the step 3 batch A tools (blacklist, SPF, redirects, header analyzer, HTML inspector, webhook tester):
   textareas, selects, data tables, stat tiles, key/value lists, code blocks, tags, notes, segmented toggles and the
   empty results state. Load it through layout_start(['styles' => ['assets/layout/tool-widgets.css']]).
   Every colour is a token, so light and dark both work. */
