work keeper-chart prefs (3) + favorites toggle + tags list + saved toggle +
session/continue — 7 routes across 5 domains, all meta_db-only (0 setattr, 0
helpers). Bodies verbatim; @app -> @router, meta_db -> appstate.meta_db,
_clean_str from reqfields.
These were scattered singletons with no natural neighbor, so they're grouped as
"small library/user-state endpoints" and mounted once. All paths are distinct
and non-overlapping, so registering them together doesn't change routing:
verified the route SET is identical to origin/main (143) AND that no moved path
shadows or is shadowed by another (order-independence check).
server.py: 7,880 -> 7,833.
Verified: pyflakes clean; route set identical + order-independent; pytest 2401
passed; packaging guard 45; eslint 0. Boot smoke: tags/session GET 200,
favorites/saved toggle (400 on missing filename), work/charts 200.
