/* Reboot Vitality GATE 1.5 close-out r2 (Y2, 2026-10-23): PHASE HUB page parts (pilot: 01 The Foundation / Reset).
   Loads after the vendor copies of the approved home (base, A, B, approved) and the interior library (interior.css).
   Style source [R25]: APPROVED/DESIGN-SPEC.md. New parts are scoped [data-variant="I"] with the rvh- prefix: the phase dial
   (the hub signature, a static paper version of the approved B phase orbit), the intro + "after the reset" strip, and the
   phase index (hub-children). Grounds come from the interior rvi-g-* classes. No @keyframes, transform / opacity only, no #000. */
