Show the last 5 received APRS frames as a compact overlay in the bottom-left corner of the waterfall strip, styled similarly to the RDS PS overlay (backdrop blur, pill border). Frames fade out by recency via CSS sibling-selector opacity steps. Bar auto-hides when empty and is cleared by the APRS clear button. Restored from localStorage on page load.
