zIndex?

optional zIndex?: number

Defined in: packages/deckgl-bridge/src/index.ts:130

Explicit stacking order for this layer within the shared MapboxOverlay, ascending (lower renders first / underneath higher values). Layers without a zIndex default to 0. Ties preserve insertion order.

Mirrors the documented z-order contract (see CLAUDE.md): heatmap 800, RTLS trails 950, bluedot 980, selection 990. Without this, layers render in plain Map insertion order — i.e. whatever order the app happened to call addLayer in — so a heatmap mounted after another data layer could silently render on top of it (see issue #982).
