find: the "[N matches for 'pattern' in path ⠠ …]" header plaque is dim
(warning color on ⠠ truncated); "No matches for …" renders dim; each match
line "{path}  ({size})" renders the path in text, "  (" and the size in
dim, and the "<dir>" marker in info.

find_up: a resolved path renders in accent; "not found (searched: …)"
renders dim.

Fallback narrowed to write/edit/append/move/copy/delete/mkdir/exists/
query/unknown. 5 new tests (find header/matches/truncated/no-matches,
find_up found/not-found); 29 filesystem-renderer tests total. Full suite
814 passed, 1 skipped.
