# Hogwarts Arithmancy Flash Cards

Interactive, themeable multiplication drill game with a Hogwarts aesthetic. Solve equations quickly to push back the “dementor” overlay, earn gold, buy cosmetics, and track mastery.

## Highlights
- Progressive levels tied to specific fact sets; mastery is earned per fact.
- Dementor pressure overlay with growing dark circles and responsive glow on keypad/equation.
- Gold + shop for skins, trails, pets; golden snitch bonus events.
- Hint grid for misses, trouble-list focus, XP → queued fact practice (no auto-master).
- Persistent progress via `localStorage`.

## Play
1) Open `index.html` in a browser (or serve the folder with any static server).
2) Tap numbers to answer; `CAST SPELL` submits, `C` clears, `⌫` deletes.
3) Earn gold/XP on correct answers; spend gold in the Student Trunk; track stats via the report card.

## Development
- Tech: vanilla HTML/CSS/JS (no build step).
- Entry points: `index.html`, `style.css`, `app.js`.
