- full-bleed: blur + translucent surface IS the overlay, no inner card;
own top bar (info + search + close, lh-no-drag so home's drag mask
never eats the X — the clickability bug)
- three levels, one click each: cluster (birth session; a chain lives in
its CONCLUSION's cluster) → chain → proposition STATEMENTS revealed
directly (names never twice; singletons one click); all collapsed by
default
- proposition names as outlined chips, → connectors between; lonely chip
= standalone proposition — the '(no premises)' annotation is dead in
the visible UI (survives only as aria-label); Folder/Waypoints icons;
rotating chevrons; deep statement indent
- real table look: hairline row + column lines; sortable Name + Created
headers (click toggles asc/desc; size is text, not a control)
- selection never shifts layout: floating bottom bar (Google-Photos
pattern) with N propositions → M chains + Clear + Generate
- fuzzy search grouped + auto-expanding clusters
