Vulnerability counts (before → after)

Tool	Severity	Before	After	Fixed
npm audit	Moderate	3	0	✓ 3
Snyk SCA	Medium (real vulns)	2	0	✓ 2
Snyk SCA	Medium (license flags)	21	21	—

Remaining issues

• 21 Snyk license flags — @img/sharp-libvips-* (LGPL-3.0) and lightningcss-linux-x64-gnu (MPL-2.0). These are platform binaries bundled by sharp and lightningcss. No fix available; require a license policy decision.
• Snyk Code findings (5) — hardcoded secrets (1 high, 2 low) and HTTP createServer (2 medium). Source-level issues; not affected by dependency updates.
• next, react, react-dom — only available upgrades are canary pre-releases; skipped intentionally.
