Squash-merge of all commits on origin/main not present on HF Space:
- fix(riprap-models): port v2 test_transform patch (services container)
- feat(map): wire TerraMind LULC + Ida 2021 HWM map layers
- fix(map): MapLegend booleans, FloodNet tier proxy
- fix(slides): deck visual fixes
- docs: live-system screenshots (now as LFS/XET pointers, not raw blobs)
- chore: repo cleanup, session artifacts to docs/sessions/
- chore: LFS tracking rules for screenshot and slide PNGs/PPTX
Binary files (screenshots + deck.pptx) are stored as git-lfs/git-xet
pointers so HF's pre-receive hook accepts them. git-xet handles
upload to XET object store during the push.
