TOPIC-051 — test instructions

ADO bug: 21816

Was failing: YouTube/Vimeo watch URLs were not normalized to embed URLs.

Fix applied: Preprocess normalizes watch?v= and vimeo.com URLs to embed/player forms.

Tester steps:

1. Edit → video embed component below → paste a youtube.com/watch?v= URL → save.
2. View page → embed renders the player.

Expected: Watch URL renders as an embedded player.
