Merged
dhh proposed and merged omacom/omarchy#16884 into Quattro, moving background intro sequencing from shell scripts into the desktop shell. The sequence holds the outgoing frame until the replacement is ready and coordinates the background link, intro playback and eventual Hyprland reload.
dhh's follow-up responses describe locking background changes against theme switches, checking intro activity while the reload lock is held, and falling back to an ordinary transition when an older running shell lacks the new handover. The changes target flashes, interrupted transitions and conflicting rapid selections.
