- New filesystem.py: make_fs() factory (returns s3fs.S3FileSystem or None),
plus fsjoin/fsstem/fsname path helpers
- config.py: storage field is now required ('local' or 's3'); load_config
raises a clear ValueError when it is missing
- video_loader, clip_selector, annotator: thread fs through all file I/O;
local paths unchanged, S3 paths use fs.open/fs.exists/fs.pipe
- annotation_script: load .env via python-dotenv at startup, create fs from
config and pass to Annotator
- Add .env.example with SwitchEngines endpoint and AWS checksum env vars
- pyproject.toml: add s3fs and python-dotenv dependencies
- Reduce default mask alpha from 40% to 15%
- Update example clip names to colon-separated timestamps

Introduce two new drawing modes alongside the existing brush:
- Polygon mode: left-click to place vertices connected by lines; right-click
removes the last vertex; clicking near the first vertex (red dot) when >= 3
points are placed closes the shape (bold cyan outline). Multiple shapes can
coexist as canvas overlays. Cancel Current Poly discards the in-progress
polygon; Del Shape removes the last completed shape.
- Fill mode: left-click inside any closed polygon to rasterise it onto the
mask. Selects the innermost shape containing the click (smallest area via
cv2.contourArea). Polygons whose centroid lies inside the target are punched
out as holes. Each fill is a single undoable step in the mask history.
Also renames the Alpha slider label to Mask Alpha and removes the stale
Reload Saved reference from the README.

- Three vertical sliders (Brightness, Contrast, Gamma) to the left of the
canvas for display-only image adjustment; all use power/linear formulae
applied on-the-fly without touching saved data
- Alpha slider controls mask overlay transparency
- Brush size slider moved to its own row
- Each slider has a reset (↺) button restoring its default value
- Hide Mask button turns red when active; Eraser button turns orange
- Load Prev Mask button copies the saved mask from the previous clip in
the list onto the current clip; the action is pushed onto the undo stack
so it can be reverted with Undo
- Right survey panel narrowed (stretch factor 2 → 1)
- README Controls section updated to document all new features

mask_canvas.py:
- Redo stack: new strokes clear it, undo pushes onto it, redo pops from it.
- undo10(): undoes up to 10 steps in one call with a single redraw.
- Brush circle preview: white Circle patch tracks mouse position and shows
current brush radius; hidden when cursor leaves the axes.
- toggle_mask() / btn_mask: hides or shows the green mask overlay without
affecting the underlying mask data.
annotator.py:
- Removed Reload Saved button and reload_saved() — clip already loads its
saved state on navigation, making the button redundant.
- Added Undo×10 and Redo buttons wired to mc.undo10 / mc.redo.
- Added Hide Mask button (mc.btn_mask) to the toolbar row.
