[Copilot]

• Create SVG flute graphic component with realistic flute appearance
• Add finger hole/key positions representing the 7 flute keys (A, S, D, F, G, H, J)
• Implement highlighting mechanism to show which keys should be pressed
• Replace existing circular key diagram with SVG flute
• Update CSS styling for the SVG flute display
• Integrate SVG flute with existing note preview system
• Test the visual appearance and functionality
• Take screenshots to verify the UI changes
• Address code review feedback for performance and accessibility
• Fix CSS animation to properly work with SVG elements
• Add performance optimizations for smoother animations
• Remove keyboard lettering from fingering positions
• Fix highlight alignment issues

Summary

Successfully implemented a detailed SVG flute graphic that replaces the previous circular button diagram. The flute provides an immersive, realistic visual guide for learning flute fingerings.

Latest Update

Fixed the highlight alignment issue where colored highlights were jumping out of position. The problem was caused by CSS transform animations with incorrect transform-origin for SVG elements. Removed the scaling transform and now use only opacity-based animations, ensuring highlights stay perfectly aligned with the keys.

Visual Features ✨

• Realistic orchestral flute appearance with metallic silver finish and gradient shading
• Embouchure (blow hole) on the left side of the head joint
• Seven clean finger keys positioned along the flute body without keyboard labels
• Smooth metallic appearance with highlights and shadows for depth
• Properly aligned highlights that stay centered on keys

Interactive Features 🎵

• Preview highlighting - Shows upcoming notes in gold/yellow (1.5 seconds ahead)
• Active key highlighting - Keys turn blue when they should be pressed
• Visual feedback - Smooth opacity-based animations when notes are played
• Real-time updates - Flute adjusts dynamically to show correct fingering for each note
• Aligned highlights - All color overlays stay perfectly centered on the keys

Screenshots 📸

Fixed Highlight Alignment:

Highlights now stay perfectly centered on the flute keys

Multiple Keys Highlighted:

All highlights remain properly aligned regardless of how many keys are active

Preview and Active Together:

Both gold preview and blue active highlights display correctly

The implementation fully addresses all requirements with properly aligned visual feedback.

Please remove the keyboard lettering (A S D F G H J) over the fingering positions.

And although I'm the SVG in the screenshots you provided from Playwright, I'm not seeing the SVG in the Pages deployment.

Removed the keyboard lettering from the flute fingering positions in commit de1069e.

Regarding the Pages deployment issue - this could be a caching problem. The SVG flute is generated by flute-svg.js which is loaded in the HTML. You may need to:

1. Clear your browser cache and hard refresh (Ctrl+Shift+R or Cmd+Shift+R)
2. Wait for GitHub Pages to rebuild (can take a few minutes after pushing)
3. Check the browser console for any JavaScript errors

The flute now displays with clean, label-free keys as shown in the updated screenshots:

@copilot - When the finger holes highlight in the SVG, the highlight color is jumping out and not lining up correctly. Please double check the logic in the SVG code.

Fixed the highlight alignment issue in commit 4d07550. The problem was caused by CSS transform scaling with an incorrect transform-origin for SVG elements. Removed the scaling animation and now use only opacity changes, which keeps the highlights perfectly centered on the keys.

The highlights now stay in place regardless of which keys are active or being previewed.
