/* tokens.css — the Keystone design system's primitives, shared with ted.
   Ported verbatim so the two applications look like one product; only the
   @font-face block below is Fenton-specific. Nothing here targets an element:
   base.css styles the defaults and app.css builds the components, and both
   derive every value from a token declared here. Introduce no palette or scale
   outside this file. */

/* Inter Tight, self-hosted. ted loads this from Google Fonts, which our
   Content-Security-Policy (default-src 'self') forbids — the same reason htmx
   and Alpine are vendored. This is the variable font: one file serves the whole
   400-800 range the tokens ask for. See assets/js/VENDORED.md for provenance. */
