 - [Phase 09-ux-tech-debt-closure]: 09-02: /printers route used for e2e test (full-page with Alpine.js) — no new /printers/new route needed
 - [Phase 09-ux-tech-debt-closure]: 09-02: conftest.py adapted — imptune.config uses string paths, init_db() takes no args
+- [Phase 11-ui-enhancements]: 11-01: Plain HTML form in printers_new.html (Option A) — no hx-post, uses action=/printers method=post so browser follows 303 redirect naturally
+- [Phase 11-ui-enhancements]: 11-01: driver_data context kept in GET /printers handler for future Plan 02 edit modal
