- Add delete notebook handler with ownership check and CASCADE delete
- Rename "Create Share Link" to "Share"
- Fix action button heights: use inline-flex + align-items for
consistent sizing across <a> and <button> elements

The web UI was linking to /v1/ REST API paths that aren't served
through nginx. Added SVG/JPG/PDF rendering and share link endpoints
directly to the web server so everything works through port 443.
- Add render.go with SVG, JPG, PDF handlers for auth and share paths
- Register render routes and share management routes in web server
- Update template links from /v1/... to /notebooks/... paths
- Add share link creation, display, and revocation to notebook view

CRITICAL:
- A-001: SQL injection in snapshot — escape single quotes in backup path
- A-002: Timing attack — always verify against dummy hash when user not
found, preventing username enumeration
- A-003: Notebook ownership — all authenticated endpoints now verify
user_id before loading notebook data
- A-004: Point data bounds — decodePoints returns error on misaligned
data, >4MB payloads, and NaN/Inf values
HIGH:
- A-005: Error messages — generic errors in HTTP responses, no err.Error()
- A-006: Share link authz — RevokeShareLink verifies notebook ownership
- A-007: Scan errors — return 500 instead of silently continuing
MEDIUM:
- A-008: Web server TLS — optional TLS support (HTTPS when configured)
- A-009: Input validation — page_size, stroke count, point_data alignment
checked in SyncNotebook RPC
- A-010: Graceful shutdown — 30s drain on SIGINT/SIGTERM, all servers
shut down properly
Added AUDIT.md with all 17 findings, status, and rationale for
accepted risks.

- HTML templates: layout, login, notebook list, notebook view, page viewer
- Web server with chi router, embedded templates via //go:embed
- Login/logout flow with session cookies
- Notebook list, page grid with SVG thumbnails, page viewer
- Share link views (same templates, no auth chrome)
- Server command wired to start gRPC + REST + web servers concurrently
- Graceful shutdown on SIGINT/SIGTERM
