Graham McIntire e74adf0036 Auto-download missing SRTM tiles, treat water areas as 0m elevation ... SRTM profiles no longer abort on missing tiles — water/ocean areas return 0m elevation instead of failing the entire profile and falling back to the rate-limited API. Elevation client and viewshed now pass download: true to auto-fetch missing tiles from S3. NFS mount changed to writable so downloaded tiles persist across pods.		2026-04-11 16:30:25 -05:00
