Applies a brand to a media, folder, or channel, so that resource is styled
by the brand's colors, fonts, logos, and layout.

A brand has no effect until it is applied to something. Media inherit from
their folder, and folders from the account's default brand, so applying a
brand to a folder styles everything inside it that has no brand of its own.

Applying the account-level default brand (is_default: true) is how a
resource is un-branded: it detaches the resource so it inherits again.

By default this also clears any brand-mapped appearance settings the
resource had set directly, so the brand is what shows. Pass
clear_overrides: false to leave those in place.

Responds with the brand now in effect on the resource, which is not always
the one you applied — detaching a media returns the brand it falls back to.

Webinars can't be branded through this endpoint yet.
