/* AdultXBlocker — Signal
   Near-black ground, one signal red. The red is the product's own colour:
   the extension's mark is a prohibition sign, and red is what a countdown
   that cannot be stopped should look like. Neutrals carry a slight
   blue-violet bias so the site and the extension popup read as one product
   (the popup's darkest tone is #1E1E22).

   Single committed theme — no light variant. Every colour is painted
   explicitly so the page holds on any host background. */
