Vessel screen hit radius	local VESSEL_POINTER_RADIUS_PX	22	main.js screen-space picking

AIS vessel markers use batched THREE.Points, not one THREE.Sprite per vessel. Moving vessels stay triangular, anchored or slow vessels stay circular, and hover / locked states add a same-size glow overlay. Vessels explicitly disable cluster and avoidance; dense areas may overlap and must not be reattached to dynamic screen clustering. Vessel type color and info-card type text must come from the same normalized result: vessels.js reads both backend vessel_type_name and AIS numeric vessel_type, derives the color-driving type, then exposes vessel_type_display for the info card, hover summary, and search results.
