Claude 18bcb192ab Fix classical playability: louder orchestra, no stacked notes

Three fixes for classical mode:

1. Louder background orchestra: bg volume boosted 1.5x in
   beginClassical so the full orchestra is clearly audible
   during gameplay, not drowned out by hit sounds

2. No more impossible stacked notes: buildClassicalNotes now
   enforces a 0.12s minimum gap between consecutive hittable
   notes. This removes physically impossible simultaneous hits
   while keeping 94-100% of notes in most pieces. Flight of the
   Bumblebee goes from 206 to 140 notes (still 4 notes/sec).

3. Balanced hit volumes: drum hits during classical mode reduced
   from gain 8 to gain 3 so they don't overpower the orchestra.
   Orchestra hit sounds boosted (strings 0.7, brass 0.4). Miss
   feedback reduced to gain 2.

Drum Rhythm Game

A browser-based drum rhythm game. Notes scroll down the screen and you hit the matching drum pad in time — like Rock Band, but it runs entirely in your browser with no server, no dependencies, no install. Just open index.html.

Works with keyboard, Wii Rock Band drum kit via USB, or any gamepad.

How to Play

Open index.html in Chrome or Edge
Pick a genre and rhythm (or a classical piece)
Click Start
Hit the pads when notes reach the line:
- F = Red (Tom)
- G = Yellow (Snare)
- H = Blue (Hi-hat)
- J = Green (Tom)
- Space = Kick (Bass drum)

Features

9 Genres: Rock, Metal, Jazz, Hip Hop, Funk, Latin, Electronic, Country, Classical
146 Rhythms: 120 drum patterns + 26 classical orchestral pieces
Classical Mode: Synthesized orchestra plays automatically while you hit the melody notes on the pads. Choose between drum sounds or orchestral hit sounds.

Leaderboard: Scores saved locally with player name, accuracy, and streak
Preview: Hear any rhythm before playing
Gamepad Support: Wii Rock Band drums via USB, auto-detected

Synthesizer

All sounds are generated in real-time using the Web Audio API — no audio files needed:

Sound	Method
Kick	Sine oscillator, 180Hz to 40Hz sweep
Snare	Highpass noise burst + 180Hz tone
Hi-hat	Highpass noise burst, very short
Toms	Sine oscillator pitch sweep
Strings	Sawtooth oscillator + lowpass filter
Brass	Square oscillator + lowpass filter
Woodwind	Triangle oscillator
Bass	Sine oscillator, low frequency
Timpani	Sine frequency sweep
Choir	Multiple detuned sine oscillators

Tech

Pure vanilla JavaScript — no libraries, no build step, no server
Single index.html file
Web Audio API for all sound synthesis
Canvas 2D for the note highway
Gamepad API for drum kit input
localStorage for score persistence
Works on Windows, Linux, and Mac
