- Move bookmark frequency markers from drawSpectrum() to drawSignalOverlay()
so dashed lines span both the waterfall and waveform canvases
- Assign distinct palette colors to named categories; uncategorised uses
--accent-yellow resolved from the live theme at runtime
- Compute WCAG-compliant foreground color (dark/light) per category so label
text is always legible against the solid background
- Add text search input to the Bookmarks toolbar; filters by name, category,
and comment client-side without re-fetching from the server
