- atlasloot_extras: fit one transform per (kg_dungeon, floor_id) instead of mixing all kg bosses into one fit. Each AL extra is assigned to whichever floor's anchors it's nearest to (in AL coord space). Strat's Stonespine now correctly lands on floor 235 (Undead) instead of being hidden because the mixed-floor fit pushed it off.
- new data/ascension_overrides.json: per-name position/floor patches for places where Ascension diverges from retail. Seeded with Magistrate Barthilas → moved to the southern courtyard (3498, 3300 on Undead Side) per Ascension spawns.
- frontend renders extras only on their assigned floor; previously hard-coded to floor 0.
- new layer-toggle checkboxes (Enemies / Packs / Patrols / Icons) in the toolbar — flip patrols off if mob routes are noise for your route.
- 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
