Replaces native title attributes with CSS ::after tooltips that appear

Show required files (audio + chart) vs optional (images) explicitly,
and mention zip support as a separate line.

Users can upload their own StepMania song bundles via drag & drop (individual
files or .zip archives) from the song selector. Tracks are parsed, displayed
in the carousel alongside built-in songs, and optionally persisted to the
browser using the Origin Private File System (OPFS). Difficulty selection and
arrow simplification are configurable per track.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
With only 4 songs, the carousel tried to show 5 positions, causing
the same song to appear twice (e.g. far-left and far-right wrapping
to the same index). Deduplicate display indices so each song only
renders once regardless of how many songs exist.

Clicking the YouTube player window shows a popup explaining why it's
there (music streamed from YouTube, ToS compliance). Spinner now uses
absolute positioning so it overlays the container instead of pushing
content aside.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Song select: spinner shown via yt-loading class, removed when PLAYING.
Game page: spinner shown via :empty pseudo-class while iframe loads.

Preview now uses YouTube IFrame API with a visible 240x135 player in the
top-left corner of the song select screen, matching the game page layout.
Falls back to local audio for songs without YouTube config.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Songs with youtubeVideoId now preview via YouTube IFrame API instead of
local .ogg files. Creates a hidden YouTube player, seeks to the preview
position (offset + 30s), and fades volume in/out on song change.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Filter SONGS export to only include songs with youtubeVideoId. All song
definitions remain in the source for future use. Vite plugin removes
non-YouTube song folders from dist after build so they aren't deployed.

For songs with YouTube config, a YT: ON/OFF button appears in the pause
menu next to KB. Toggling it recreates the audio player so you can
compare YouTube vs local audio during the same session.

Raw PCM cross-correlation fails on different masters/mixes (all candidates
have near-identical confidence). Chromaprint generates perceptual hashes
that are invariant to mastering, so the correct offset is always in the
top 2 candidates with clear separation. Still generates comparison WAVs
for ear verification since repetitive songs can have ambiguous top picks.
Requires fpcalc (chromaprint) on PATH in addition to ffmpeg.

Offsets verified by ear using comparison WAVs:
- Chop Suey: GK-DkHHAMIU offset 8.968s
- Just Dance: 5q7byFPTehs offset 0.062s
- Meet Me Halfway: -GY8MhHMxLM offset 6.973s
Also fix offset tool: handle video IDs starting with '-' via --yt flag,
skip negative/empty offset candidates in WAV generation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Correct offset from 66.389 to 0.207 (was matching repeated section).
The tool now generates stereo comparison WAV files (left=local,
right=YouTube) for each candidate so you can verify by ear.

YouTube ToS requires the embedded player to be visible (min 200x200px).
Place it in the top-left corner at 240x135 with rounded corners and a
subtle border. Player fills its container and is non-interactive
(pointer-events: none) so it doesn't interfere with gameplay.

Pause menu now has a KB button next to LOG. When enabled:
- Arrow keys feed steps directly into the game
- Calibration is bypassed so the game starts immediately
- Camera-based step detection and auto-pause are disabled

Replace direct HTML5 Audio usage with an AudioPlayer abstraction that
supports both local audio files and YouTube IFrame Player API. Songs
can now specify a youtubeVideoId and youtubeOffset to stream audio
from YouTube instead of hosting audio files.
- AudioPlayer interface with LocalAudioPlayer and YouTubeAudioPlayer
- YouTube IFrame API type declarations and script loader
- Cross-correlation offset detection tool (tools/audio-offset/)
- Get Lucky configured with YouTube video 5NV6Rdv1a3I, offset 66.389s

and scrub controls. Test page at /recording-test loads JSON via file picker.
Also added download button to /record results.
