/* Broank Tools: the one look every page on tools.broank.com shares (tools-site/README.md → "The look").
   Colours are Broank's own (modern/src/styles/app.css), so a tool feels like the app. A tool's own CSS may lay out its
   page, but takes every colour, radius, shadow and font from here, and never sets its own accent. */
