Two fixes from user feedback on the hydrology view: 1. Rivers looked too sparse. Investigated coupling rainfall into discharge (climate precip -> river rainfall): it does NOT work as hoped because river *location* is set by drainage topology (where water collects), not local rainfall -- weighting rainfall mostly changes river *size*, and concentrating a fixed water budget pushes mid-size rivers below the display threshold, so FEWER rivers show. Reverted that approach. Instead lower the default riverThreshold 50 -> 25 so tributaries render too: a richer, more visible network (~2x river cells on test worlds) without descending into noise. Tunable in planet.cfg. 2. Clicking a tile overlaid a low-res, always-elevation-coloured subgrid patch on the 3D globe that clashed with the active colour mode and read as a "strange pattern". Removed the globe overlay; the clicked tile's high-res subgrid still shows in the right-side detail panel. test_logic + test_biota pass; full app builds clean.
