You've been to dozens of concerts, festivals, and local gigs — but the memories blur together. **Gig Bag** is a single-page app that lets music fans log every live show they've attended, so nothing gets forgotten.

Each show entry captures:
- **Artist / Band name**
- **Venue and city**
- **Date of the show**
- **Setlist highlights** (a freetext field for songs you remember)
- **Personal rating** (1–5 stars)
- **A short memory note** (one moment, one feeling)

The app displays all logged shows as a scrollable card list, sorted from most recent to oldest. Each card shows the artist name, venue, date, and star rating at a glance, and expands (or opens a modal) to reveal the setlist highlights and memory note.

Users can **edit** any show entry and **delete** entries they added by mistake. A small summary banner at the top shows total shows logged and the user's most-seen artist (the name that appears most frequently across entries).

All data persists in `localStorage` so the journal survives page refreshes. No login, no backend — just a personal concert history that lives in the browser.
