 ## Dev Agent Record
 ### Agent Model Used
-<!-- dev-agent: record model/version used during implementation -->
+dev-agent: assistant (Cline persona) — model: gpt-4o (used to plan edits and generate code changes)
 
 ### Debug Log References
-<!-- dev-agent: link to any debug logs or traces generated -->
+- No runtime logs generated. Edits performed to source file `components/artist-portfolio.tsx` and this story file.
 
 ### Completion Notes List
-<!-- dev-agent: notes about completion, issues encountered, resolutions -->
+- Implemented category filter controls (buttons) and wiring to filter portfolio items.
+- Replaced gallery img tags with Next.js `Image` to provide explicit dimensions and reduce CLS.
+- Implemented accessible lightbox modal with keyboard navigation (Esc, ArrowLeft, ArrowRight), focus return, and visible controls.
