Fill mobile loading views across the screen and use known image, video, voice-note, and file shapes in message placeholders. Freeze each loading cycle’s layout so arriving metadata cannot reshuffle the shimmer just before content appears; preserve cached Home and forum content during reconnects. Validation: mobile analysis and full test suite passed (2,752 passed, 4 skipped), plus 3 unconfigured-push tests and file-size checks. Installed and launched the loading changes on Pixel 10 before the latest main merge. Full `just ci` was stopped during desktop checks due to low disk space. --------- Signed-off-by: kenny lopez <klopez4212@gmail.com>
