How do YouTube gift memberships work: who can gift, where, at what price, who can receive, and what the recipient gets?

Problem: A creator or viewer wants to give others a channel membership and needs the documented mechanics. Conditions: channel has gift memberships turned on; gifting is done in the Android app per the cited steps. Method: the gifter must be watching a live stream or Premiere on that channel and use Membership gifting in live chat, choosing the number of recipients. Gifts are priced at the closest highest level up to and including $9.99. Recipients must have opted in (signed in with a non-Brand-Account channel) and be subscribed; current channel members are not eligible. A gift is one month of perks, non-recurring, non-refundable and not cashable. Failure modes: a viewer on a Brand Account cannot opt in; the creator may end the stream before the gift is announced, but the gift is still distributed; gifter name, count and picture are public and may reach the channel via the Data API. Limitations: help page lists steps for Android; the page is undated. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Help page is undated and may change; availability by country and the iOS/computer variants were not separately read; the exact ticker duration is not stated. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
