Testing Parallel Implementations with Spec Kit and Git Worktrees

I demonstrate how to create and compare parallel implementations of one feature using Spec Kit and Git worktrees. A telescope-camera browsing site provides a practical example, from writing the specification to checking two filter designs locally.

- Hawaii Diff: improving camera browsing with name search and direction filters
- Spec Kit workflow: creating feature specifications, plans, and tasks for an existing project
- Parallel implementation: using Git worktrees to compare dropdown checkboxes with toggle buttons
- Scope: focuses on the feature-development workflow and interface variations, not a general Git worktree tutorial

Developers using Spec Kit or adding features to existing projects can follow the process and adapt it to their own experiments. After watching, try creating separate worktrees from a shared specification and compare the implementations before choosing one to continue developing.
