#96880 reserved `pr-9` on every closeable tab so the hover ✕ could never
sit over a label — 36px of empty runway at rest on every tab, nearly
doubling FILES (40→76px) and taxing tabs whose label already cleared the
overlay by a mile.
Restore the overlay as designed (✕ paints over the label's right edge,
gradient-blended, zero layout shift) and protect short labels with a
`min-w-13` floor instead. Sized from the chrome it has to survive: 8px
label inset + the ~19px opaque chip, so the shortest labels clear the
chip and pass only under the translucent fade. A floor bills only tabs
that need it; TERMINAL, BROWSER, NEW CHAT pay nothing.
The test that pinned `pr-9` by class string is rewritten as a set-diff
contract: adding `onClose` must add a `min-w-*` and never a `pr-*`.
