"Projects / work / / Conversations / init" had no missing label.
Every project crumb link had min-width:44px, so a short name such as
"work" was padded with blank space after its text, and the separators
around it read as an empty crumb. The 44px target width now comes
from an ::after overlay centred on the link, so the layout box fits
the text on every project route.
The new browser test measures text-to-separator gaps and hit width
on the overview, conversations and conversation routes at 1440 and
390px. It fails on 6ca7f3b65 and passes here.
