CARTO Basemap Removal Fix

Date: 2026-10-08
Issue: "API KEY REQUIRED" watermark appearing in the Cobb County Tree-Risk Monitor hero panel.

Root Cause

The Leaflet map was loading a CARTO basemap tile layer (basemaps.cartocdn.com/dark_all/...). CARTO's free tier now requires an API key and displays a watermark when one is not provided. The watermark text read carto.com/basemaps/apikey.

RainViewer radar tiles were rendering correctly — they require no API key.

Changes Made

`weather-panel.js`

Removed the CARTO L.tileLayer(...) basemap call entirely.
Set host.style.backgroundColor = "#1c1f1e" on the map container so the map area renders as a plain dark canvas instead of a blank white void.
Attribution updated to RainViewer only:
'Weather data by <a href="https://www.rainviewer.com/" ...>RainViewer</a>'
OSM and CARTO attribution strings removed.
Cobb County outline, HQ marker, and RainViewer radar layer left untouched.

`site.css`

Updated stale CSS comment from /* Required OpenStreetMap / CARTO credit — kept small and faint */ to /* Leaflet attribution — RainViewer credit only (no basemap) */.
