/* Website Launcher — First Signal brand v2.0.
   Colour and type come from fs-tokens.css, vendored verbatim from the First Signal marketing
   repo so any drift from the locked brand is visible as a diff rather than hidden in edits here.
   Fonts are self-hosted: this app's CSP allows no external styles or fonts, and a customer
   portal should not announce its visitors to a third party. */
