Mini Articles (<=14KB)
- Single-file site: `index.html` with inline CSS & JS
- Features:
- List of articles with thumbnails (cards)
- Read view: thumbnail, title, body (supports inline images/videos)
- Create view: title, thumbnail picker/drag-drop, rich body via contenteditable
- Drag/drop or choose images/videos anywhere in the body
- Local persistence via localStorage (no server required)
How to open
- Open `site/index.html` in a browser.
Tests
- `pytest` includes a test to enforce the 14KB budget for `index.html`.

## Sliding-Square Puzzle Solver
Parses a screenshot of a sliding-square puzzle and solves it via BFS.
### Setup
```bash
cd puzzle_solver
python -m venv .venv && source .venv/bin/activate
pip install opencv-python-headless numpy
```
### Usage
```bash
# From workspace root, with venv active:
# Step 1 – Parse screenshot to editable JSON
python -m puzzle_solver parse screenshot.png -o puzzle.json
# Step 2 – Review & fix any "unknown" squares in puzzle.json
# (set "type" to: normal / portal / teleporter / key / lock)
# Step 3 – Solve
python -m puzzle_solver solve puzzle.json
# One-shot (no manual review)
python -m puzzle_solver run screenshot.png
# Debug overlay (visualise detected squares on image)
python -m puzzle_solver debug screenshot.png -o debug.png
```
### Game mechanics
| Square | JSON type | Description |
| ------------------- | ------------ | ------------------------------------------------- |
| Empty outline | `normal` | Regular landing square |
| Solid fill | `player` | Starting position |
| Ring inside | `goal` | Target destination |
| Inner square offset | `portal` | Pass through from the side marked by `"side"` |
| Antenna line(s) | `teleporter` | Warp to paired teleporter (`"group"` id) |
| Key symbol | `key` | Removes matching lock (`"lock_id"`) |
| Lock symbol | `lock` | Solid until matching key collected, then vanishes |
### Movement
You slide in a cardinal direction (up/down/left/right) until you hit
another square. If you slide off the grid without hitting anything, you
die.
### Algorithm
BFS over state = `(position, set_of_active_locks)`. Explores all
reachable states and returns the shortest move sequence to the goal.
