Build a complete drop-disc four-in-a-row game called "Four in a Row" as a single HTML file that runs in a phone or desktop browser. Use original names and art only; do not copy any existing game's branding.

Opponent: Computer.
Computer skill: Medium (ignored when playing a friend).
Disc colors: Red and yellow.

Rules:
- A 7-column, 6-row upright board. Players take turns dropping a disc into a column; it falls to the lowest free spot.
- First to line up four discs in a row, column or diagonal wins; highlight the winning four. A full board is a draw.
- Easy computer plays semi-randomly; Medium looks a few moves ahead; Hard searches deeper (minimax with alpha-beta).
- Tap a column to drop. Show whose turn it is. Rematch and New game buttons.
- Computer replies after a short delay so the player can follow.

Make it feel great: discs fall with a bounce, the winning four pulse, the board is large and fits any phone.
