MASTER PROMPT / REBUILD RECIPE (v3.2.67):
"Create a Tampermonkey script for YouTube that adds a persistent, draggable speed control overlay with a License/Pro system.
Core Features & UI:
- Precision Controls: Granular slider (0.05 increments) and presets (Pause to 2x).
- Custom Logo: Must use specific SVG paths (lp1, lp2, lp3) with Transformation Matrix (6.201...) and colors (#ff0000, #ffffff). Acts as a minimize toggle with hold-to-manage license logic.
- Transparency: 25% step toggle using a dynamic SVG pie-chart icon; persists via localStorage.
- Smart Tooltips: 0.8s transition delay, 11px normal weight text, and 'Smart Boundary' logic to auto-flip orientation at window edges.
- Color Palette: Primary text/icons #888888; Slider thumb dark red (#880000) switching to bright red (#ff0000) on hover. Pro 'Override' state uses green (#00ff00).
Layout & Structure:
- Main Container: Flexbox row alignment with 8px gap. Background: rgba(0,0,0,0.8) with 8px border-radius.
- Minimized State: When minimized, the container shrinks to only the Logo. A dedicated drag handle (dots icon) must appear to the left of the logo only when minimized to allow repositioning.
- Pro Button Group: A dedicated sub-container (.pro-btns) using 'display: flex; gap: 3px; flex: 1; overflow: visible !important;' to house Pro toggles.
Pro Features (License Key Required):
- Chapter Navigation: « and » arrows with fixed -2.1px top offset and 18px font size.
- Auto-Speed Logic: Context-aware 1x speed override for 'Music', 'Movies', and 'Shows' categories.
- High-Fidelity Audio: 'P' toggle to disable YouTube's pitch correction (preservesPitch = false).
- Analytics: Lifetime 'Time Saved' tracker based on playback rate vs. actual duration.
Logic & Correctness Constraints:
- Vertical Centering: Pause button text wrapped in a span with -1.8px top nudge for visual balance.
- Playback Preservation: Toggling Pro buttons (Music/Movies/P) while paused must never trigger auto-resume.
- License Guard: checkLicense() must immediately disable all Pro logic and reset audio fidelity if the key is removed.
- Persistence: LocalStorage must remember speed, coordinates, opacity, settings, and minimized state."
