   Continuum Pocket RX - Mobile shell styling
   Kernel-owned stylesheet (same convention as qrx.css / aria.css):
   guest apps never depend on these rules. Reuses the neon design
   tokens defined in core.css (:root) for visual continuity with
   the desktop shell and Q-RX.

/* On a phone-sized/mobile-UA browser, Pocket RX always lands in a temporary
   session (see kernel.js _runBootSequence), so the desktop-only "connect an
   empty directory" install path and the download/community promo row never
   apply — only the one-tap temporary-session start remains. */
