Summary

• The menu bar icon was a code-drawn SF Symbol (waveform), unrelated to any image asset — so updating the app icons in Resources/ never affected it.
• Replaces it with a monochrome template glyph that mirrors the app logo (speech-bubble ring + tail + waveform), embedded as a base64 PNG and flagged isTemplate so macOS auto-tints it for light/dark menu bars.
• Recording/transcribing states keep their distinct status symbols (record.circle / ellipsis.circle).
• Removes the now-unused StampedMenuBarIcon and the dev-only icon variant.

Notes

• The glyph was authored as a clean vector-style silhouette (a raw raster trace of the full-color logo collapses into a solid blob) and visually verified at menu bar size on light and dark backgrounds before embedding.
• This unifies dev and release menu bar icons — the previous dev-only distinct icon is gone. A small dev marker can be re-added if desired.

Testing

• Not built in CI here (Linux sandbox lacks macOS AppKit/SwiftUI). The embedded base64 decodes to a valid PNG and the Swift is structurally sound; please run a local make build to confirm appearance in the menu bar.

Summary by CodeRabbit

• Bug Fixes
  • Updated the menu bar icon to render more reliably, with a fallback icon if the custom image can’t be loaded.
  • Improved icon selection so the app now shows the correct menu bar symbol in different states.

📝 Walkthrough

Walkthrough

MenuBarLabel now renders its icon through a dedicated view builder, and the custom menu bar glyph is built from embedded base64 image data with a system-symbol fallback.

Changes

Menu bar icon refactor

Layer / File(s)	Summary
Icon selection Sources/App.swift	MenuBarLabel now renders the active icon through a @ViewBuilder property and still conditionally shows the checkmark with the same animation values.
BubbleWave image Sources/App.swift	BubbleWaveMenuBarIcon now creates its template NSImage from an embedded base64 PNG and falls back to waveform.circle if decoding fails.

Poem

A bunny hopped by the menu bar light,
With a bubble-wave icon looking bright.
If PNG dreams fade,
A symbol is made,
And checkmarks still sparkle just right. 🐇
