The welcome card is gone. The full-screen splash is the start screen for both
frontends, shown whenever nothing is open — Begin, the last project, the full
project list (with import), and the maintenance actions. "Load an existing
project" now opens a picker inside that surface instead of handing off.
Chrome type follows Apple's conventions: group headers, field labels, tabs,
segmented controls, lane names and status chips are sentence-case system sans,
sized on the scale, with no letter-spacing. Monospace is now reserved for data —
timecodes, counts, paths, prompts, node classes — which is what it was doing in
the timeline ruler all along. Zone padding moves onto the 4pt grid.
Scene length/fps modes read "Project default" / "Timeline trim" instead of
labels too long for their control.
