/* ── Inline mode ──────────────────────────────────────────────────────────────
   A host that already HAS a place for the assistant — the passenger portal's
   "AI Dispatch" tab is a whole screen of it — does not want a floating bubble
   sitting on top of its own layout. Setting data-pba-inline on #pba-root drops
   the launcher and renders the panel in flow, filling its container.

   No JS change: build() still creates the launcher and leaves the panel closed,
   and both of those are decided here. The runtime gate is untouched — nothing
   below applies until the script adds .pba-ready, which it only does after
   booking-agent.php?status=1 reports enabled.

   These selectors carry an id + an attribute, so they outrank the .pba-panel
   rules inside the max-width:480px block above regardless of source order. */
