fix(site): wall hover arrow loses to extracted-CSS order in production.

The base arrow rule and its hover override tied at specificity (0,2,2),
so whichever the extractor emitted last won; production chunk order
emitted the hover rule first and the accent never applied. Out-specify
the base instead of tying with it, same medicine as a.stat above.
