/* squ.solutions · v5
   The grammar of a personal product-portfolio site — fixed floating pill
   nav, a full-viewport hero with the name anchored at the bottom, a light
   "selected work" section of gradient cards with device frames, a dark
   band, an about block, and a giant say-hello footer — carried over to a
   pricing/FP&A practice. Display face Bricolage Grotesque, body Inter,
   labels Geist Mono; all three SELF-HOSTED as subset variable WOFF2
   (no font CDN — blocked where this is authored). The reference's azure
   pulled a step darker throughout. */
