Roborazzi draws Library (phone, tablet, font scale 1.5, empty), a title,
Shares, Settings and Downloads from fixed records under Robolectric, and
build-android.sh check compares them with the committed images in
app/src/test/screenshots. The redesign changes every screen; a layout
regression now fails the gate and shows up in review as a changed image.
- libmpv is built in its own step and saved with actions/cache/save right
after, so a failure later in the job no longer discards a 12 minute
build the way a post-job save did
- lint's OldTargetApi fails the gate whenever a new platform ships, like
the dependency freshness checks already marked informational; raising
targetSdk is a deliberate change with its own device pass
