Lint's AppLinkWarning failed the gate: a BROWSABLE https filter reads as an
App Link missing autoVerify. It can never be one, since drive.proton.me is
Proton's domain, so the attribute now says so.
A drive.proton.me/urls/ link opened from a browser, or text containing
one shared to the app, switches to Shares and opens the Add form with
the link filled in, fragment included. A playing episode moves to the
mini transport instead of covering the form. A recreated activity does
not offer the same link again.
The view filter is not autoVerify, since the domain is Proton's, so
Android only routes browser links here once "Open supported links" is
allowed in the app's settings; sharing works without that.
The icon follows proton-drive-linux's logo: a violet gradient tile with
a darker lower edge, and a white play mark with a soft shadow, cut into
the blocks a revision is fetched in. The SVG, the window PNG and the
Windows .ico are rendered from one source.
On Android it is an adaptive icon with a monochrome layer for themed
icons, and the notification glyph is the same mark. The app is named
"Proton Stream"; the launcher shows "Stream", since "proton-stream" was
cut to "proton-st…".
