"""Phase 1.5 (#4717): empty/zero-conversation profile shows a quiet empty-state
|
||
|
|
skeleton on switch instead of a misleading content skeleton.
|
||
|
|
|
||
|
|
These are source-level structural guards (the skeleton logic is browser JS; the
|
||
|
|
behavioural check is a manual browser pass documented in the PR). They pin that
|
||
|
|
the per-profile count cache + the empty-branch wiring exist and are connected, so
|
||
|
|
a refactor can't silently drop the empty-profile affordance.
