Migrate the DaisyUI component $ARGUMENTS into a WebX templ component.

Follow the migration guide at docs/component-migration-guide.md exactly. Read it first before writing any code.

Steps:

1. Look up the component on https://daisyui.com/components/$ARGUMENTS/ to understand its HTML structure, CSS classes, modifiers, and whether it uses a hidden input (checkbox/radio) or <details> for interactivity.

2. Determine the tier:

   • Tier 1 (CSS-only) if purely visual/structural
   • Tier 2 (Interactive) if it toggles, shows/hides, or changes state

3. Create the package at ui/$ARGUMENTS/$ARGUMENTS.templ following the tier template from the migration guide.

4. Map all DaisyUI modifiers to typed Go consts (Variant, Size, Position, etc.).

5. For Tier 2 components: define a signals struct, use utils.Signals(), and use ds.* helpers for ALL Datastar attributes. Never write raw data-on-click or similar — always use ds.OnClick(), ds.Attr(), etc.

6. Generate and build:

   sh
   1go tool templ generate
   2go build ./cmd/showcase

7. If the component introduces new DaisyUI classes not yet in the codebase, rebuild CSS:

   sh
   1go tool gotailwind -i static/css/input.css -o static/css/output.css

8. Create a showcase page at cmd/showcase/internal/pages/$ARGUMENTS.templ demonstrating the component with multiple variants/sizes. Register the route in cmd/showcase/main.go and add a sidebar link in layouts/showcase.templ.

9. Write an E2E test at tests/e2e/$ARGUMENTS_test.go. For CSS-only components, verify elements render with expected classes. For interactive components, verify toggle/state behavior using Playwright.

10. Run E2E tests to verify:

    sh
    1go test ./tests/e2e/... -run $ARGUMENTS -v
