## CI linting, accessibility, and fetch hardening ### Added - Ruff linting and format checks in CI (`ruff check .`, `ruff format --check .`) - Expanded ruff lint rules: `UP` (pyupgrade), `B` (bugbear), `SIM` (simplify), `RUF` - ARIA attributes: `aria-live="polite"` on flood status, `aria-busy` on refresh button, `role="button"` and `aria-expanded` on flood warnings summary - `prefers-reduced-motion` media query — disables spinner, warning pulse, and log slide-in animations - Response validation (`if (!resp.ok)`) on all `fetch()` calls (GeoJSON overlays, EA API, flood warnings, backend sync) ### Fixed - Red console error (`OPTIONS 405`) on every page load from backend detection — switched to silent `XMLHttpRequest` - Data freshness timestamp and flood status delayed ~2s on load — show timestamp immediately after markers, run network probes non-blocking ### Changed - Pre-commit hooks now filter to Python files only (skip JS/CSS/JSON/GeoJSON) - Expanded `.gitignore` with standard exclusions (`.env`, `venv/`, IDE dirs, `*.log`) - Applied ruff auto-fixes: `timezone.utc` → `UTC` alias, removed redundant `"r"` mode args
