`<HeroStrip>` (v1.4.20 phase B1) replaced this component on every
surface. Last production import was retired with the dashboard rewrite
and only the deprecated source + its self-test remained. Comment
markers in `hero-strip.tsx` already note the migration.
Pre-existing typecheck failures in the working tree (locale enum drift
from concurrent W9e i18n work in medication-card / medication-form /
target-card) are unrelated to this delete and stay as-is.
