Using the pre-provided tone.min.js (global Tone), build a playable piano keyboard controlled by mouse and computer keys that synthesizes notes with an ADSR envelope and visual key feedback.
I'll create a single-page web app with a playable piano keyboard that responds to both mouse clicks and keyboard presses. The app will use the Tone.js library for audio synthesis with ADSR envelope and provide visual feedback for pressed keys.

I need to complete the keyboard mapping and finalize the JavaScript code for the piano app. Let me continue with the remaining keys and close the script properly.

I'll fix the overlapping edits by merging them into a single edit that properly completes the keyboard mapping and adds the necessary event listeners for keyboard release and note stopping.

The piano keyboard application has been successfully created with all required functionality: 1. A visually appealing piano keyboard with white and black keys 2. Mouse interaction - click and hold to play notes with visual feedback 3. Keyboard interaction - use the mapped keys (a, w, s, e, d, f, t, g, y, h, u, j, k, o, l, p, ;, q, i, r, o, p, [, ]) to play notes 4. Visual feedback for both mouse and keyboard input 5. ADSR envelope applied to the synth for natural note decay 6. Proper note stopping when keys are released The application is fully self-contained in a single HTML file with no external dependencies other than the provided tone.min.js library. All functionality is implemented with inline JavaScript and CSS as requested.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
