### Changed

- Renamed the project focus from a workout/nutrition tracker to a medical tracker and medical reference database.
- Reworked the homepage from a marketing-style landing page into a direct medical reference hub.
- Reworked `/nutrition.php` from nutrition tracking content into the medicine catalog route.
- Reworked `/workouts.php` from workout planning content into the condition database route while keeping the legacy URL for compatibility.
- Reworked `/medical.php` into a combined searchable library for symptoms, terms, conditions, medicines, and study links.
- Reworked medicine and terminology list views from dense cards into compact searchable directory rows with dynamic detail links.
- Updated profile management so public profile creation is no longer part of the site flow; profile creation is handled through admin/tracker tools.
- Updated `README.md` to match the current medical-reference app, current routes, current data counts, source update process, and API actions.
- Preserved legacy fitness, nutrition, supplement, routine, workout, and body-metric data structures as optional wellness context inside the tracker.

### Removed

- Removed the public signup form and public signup JavaScript.
- Removed the `public_signup` API action.
- Removed signup links from the public header, footer, homepage, and condition pages.
- Removed unused signup/showcase CSS from the public stylesheet.
- Replaced `/signup.php` with a simple redirect to `/tracker.php` for legacy links.

### Fixed

- Fixed text overflow on long medicine names, chemical names, brand lists, source URLs, and compact database rows.
- Fixed searchable medicine and terminology pages so entries have shareable dynamic pages instead of only inline catalog cards.
- Fixed condition and symptom search behavior so relevant name matches appear first.
- Reduced one-time SQLite seeding lock risk by wrapping symptom catalog seeding in a short transaction and skipping once populated.

### Verified

- Verified dynamic medicine, symptom, condition, and terminology routes return `200` for representative records.
- Verified legacy `/signup.php` returns `302` to `/tracker.php`.
- Verified `api.php?action=public_signup` returns `404`.
- Verified current SQLite snapshot counts: 6,002 medicines, 242 symptoms, 203 conditions, 23 terms, and 9 research-link categories.
- Verified browser layout checks for medicine, symptom, and terminology pages at desktop and mobile widths with no horizontal overflow.
