Strip box-drawing (──) section dividers and ===/banner headers — visual
noise with no information. Where a divider label carried a non-obvious
why (VirtualList owns scrolling; mobile footer is md:hidden because header
stats take over) it is kept as a plain one-line comment; pure restatements
of the markup (Header bar, Red hover line, Bottom: fixed controls) are
dropped. Single comment style, no fluff.
DisplayFont was not a feature (FSD+ A-6): the whole slice was one
presentational component that renders a Font styled by typography, with no
model/domain/action. To get typography it reached sideways into a sibling
feature (`$features/AdjustTypography/model`) — a feature->feature edge
(C-1), the symptom of the mislayering, not the disease.
Fix by inversion, mirroring the existing `status` prop pattern:
- move FontSampler into entities/Font/ui (it now uses only entity siblings
+ $shared/ui)
- it accepts a `typography` prop typed to a minimal contract defined in the
component; the AdjustTypography store satisfies it structurally, so the
entity has no dependency on the feature
- SampleList (owns both) injects its typographySettingsStore as the prop
- delete the DisplayFont slice; export FontSampler from the Font barrel;
relocate the story (now passes a mock typography)
Resolves A-6, A-7, and the FontSampler half of C-1. Verified: 0 type
errors, 0 lint (boundary rule satisfied), 905 unit + 213 component tests,
production build OK.
