/* 1NFINIT3 FRONT SHELL — QUALIFICATION CANDIDATE
   Owner locks implemented here:
   - root entrance is a fixed viewport, not a scrolling landing page
   - no full-width top navbar/header slab
   - small canonical wordmark centered to the viewport
   - phone drawer overlays only part/about half of the live workspace
   - internal regions own scrolling; body does not
   Exact breakpoint/drawer/gesture measurements remain QALS-unfrozen until real-device qualification.
