3rd tightening pass (series LRN-1005/1007): bare "ux" matched inside
French prose (2 logged FPs, both FR — latest "changement ux vu").
\bui\b kept: zero logged FP, one logged true positive, now locked by a
must-fire test row. Flip-tested: quiet row fired pre-change.
The 07-02 tightening left bare tokens common in non-UI talk (design, component, theme, transition, frontend, palette) -> ~6 false-fires/session during the ECC config audit. Dropped them; dashboard now word-boundary matched (kills the ecc_dashboard.py filename match, keeps 'admin dashboard'); kept animation; added 'front-end design' bigram. Each fire now logs time+token+excerpt to a light file so 're-firing?' is measured, not argued. Regression test 18/18, shellcheck clean.
