- replaced SVG <title> tooltips (which use the OS dwell-delay) with an instant custom tooltip rendered in #custom-tooltip
- note pins now also render their text inline next to the icon, so a route can be read at a glance without hovering each pin (truncated at 80 chars in the SVG; full text still in the tooltip)
- classification 5 (rare-elite) now renders with silver-blue skull pin and shows up in the boss list with a 'rare' tag (was falling through to default trash style)
- new Note tool: click map → enter text → drops yellow info pin; hover for tooltip, double-click to edit, drag to move, right-click to remove. Notes are included in the share-URL hash and history.
- Clear button now confirms before wiping the current floor's waypoints/pulls/notes
