/* ---------------------------------------------------------------------------
   Landing page styles. Deliberately a linked file rather than a <style> block:
   a linked stylesheet is covered by `style-src 'self'`, so this page needs no
   'unsafe-inline' anywhere. See landing/_headers.

   Tokens mirror src/styles.scss so the page and the app look like one thing.
