New internal/web package mounted at /ui/, separate from DAV Basic Auth: - Cookie-based sessions (opaque random tokens in a new web_sessions SQLite table, internal/db/sessions.go), checked against the same cfg.Users/bcrypt credentials as DAV Basic Auth. - Dashboard listing the logged-in user's own calendars/address books, who they're shared with, and what's shared with them. - Share/unshare directly from the dashboard, updated in place via htmx partial swaps (POST to create/update, DELETE to revoke). Always verifies the resource actually belongs to the logged-in user before granting a share. - Templates written in templ (internal/web/templates/*.templ, generated *_templ.go committed), styled with Tailwind CSS v4 (web/input.css, compiled to web/static/app.css), with htmx vendored as a static file for the dynamic bits. Both are embedded into the binary at build time (web/staticassets.go) so the compiled server has no Node.js/web/ runtime dependency. - Wired into cmd/server/main.go at /ui/ alongside the existing /cal/, /card/, /files/ routes; welcome page links to it. - Tests: internal/web/server_test.go covers login success/failure, the login-required redirect, dashboard rendering, share/unshare including the htmx-v2-sends-DELETE-params-as-query-string quirk, and rejecting shares of resources the user doesn't own. - Docs: README (new 'Web UI' section, updated sharing section, project layout, dependencies) and copilot-instructions updated accordingly. Makefile: new templ-generate/web-deps/web-css targets. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
