/* phenlabs.com coming-soon page (2026-10-01).
   The platform's design system (public/css/system.css) in miniature: black, white, one deep blue,
   1px hairlines, Geist Mono as the voice and Aeonik for the wordmark only. Self-contained on purpose:
   this host serves nothing else of the platform, so it cannot load system.css.
   ⚑ Both typefaces are SELF-HOSTED: no request leaves for Google Fonts, so a visitor's IP reaches no third
     party for a font, and the CSP allows 'self' only. Geist Mono is the OFL variable font from Vercel's
     `geist` npm package 1.7.2 (fonts/GeistMono-OFL.txt travels with it, as the licence requires). */
