/* Know Halal website, 5 Oct 2026.
   Plan from the frontend-design skill (github.com/anthropics/skills): one type family, the app's own
   colours, and one bold element (the ingredient label in the home page hero). Everything else is quiet.
   Colours are the app's light theme (app/src/theme/tokens.ts) so the site and the app look like one product. */
