/* Define, Inc. — definesignal.ai marketing site.
   MAL-140 build. Recreated pixel-faithfully from the Design v2 handoff
   (prototype/site.jsx + reference build), content FINAL per MAL-139.

   All styling lives here (no inline style="" attributes, no inline <style>),
   so the served CSP can stay style-src 'self' with no 'unsafe-inline'.
   One mobile breakpoint at <760px, matching the prototype's useMobile() hook,
   recreated with a media query per the handoff README. */
