/* Stitchen landing page — single-file CSS.
   Brand colors: cream #F7F2E8 background, navy #1F2C49 ink, salmon
   #D96A6A accent. Matches the Flutter app's theme so the page and
   the app feel like one product.

   Visual posture: toned down, not corporate-clinical. The brand
   banner does most of the lifting at the top; body type stays
   relaxed, with cross-stitch "x" accents standing in for bullets
   so the page reads like the app's adjacent surface rather than a
   generic SaaS one-pager. */
