Iframe embed + page script

The same iframe, plus the optional page.min.js on the customer page. It is what makes fullscreen work when the frame sits inside a transformed or clipped container.

Player runs on	`control.jefflowery.dev` — third-party to this page
Config comes from	query params on the frame src, mapped to `data-*` by `standAlone()`
Sign-in transport	iframe, escalating to a popup when storage is unreachable
This page can read the viewer id	no — the result is addressed to the player’s origin
Extra on the customer page	`page.min.js`, which listens for the player’s fullscreen messages and resizes the frame

The markup

<iframe
  src="https://control.jefflowery.dev/webplayer/video?identifyViewer=required&id=…&type=event"
  allow="autoplay; fullscreen"
  allowfullscreen="true"
  title="Resi player"></iframe>

<script src="https://control.jefflowery.dev/webplayer/page.min.js"></script>

Expected

Sign-in behaves exactly as the plain iframe case — the page script has nothing to do with identity.
The log below shows the player’s PLAYER_READY and FULLSCREEN_ENTER / FULLSCREEN_EXIT messages, and the page script acts on them.
This is the page to compare against when a customer reports fullscreen breaking but playback working.
Still no viewer id in the log.

Messages reaching this page

This case exists partly to show what the parent is supposed to receive. PLAYER_READY and the fullscreen messages are the real contract; the sign-in result is not, and never appears here.
