# Test Evidence: dark icon sprite presentation

- **Test type:** Web
- **Requirement IDs:** `UI-006`, `UI-009`, `UI-010`, `UI-018`
- **Scenario IDs:** `AC-UI-003`, `AC-UI-005`
- **Test class/method:** `com.lab.labtimesheet.ui.UiContractWebTest#generatedLucideSymbolsRetainCurrentColorStrokePresentation`
- **Implementation commit:** `pending`

## Protected behavior

Every local Lucide sprite symbol retains the source presentation attributes so icons referenced with `<use>` inherit `currentColor` rather than rendering with the SVG default black fill on dark surfaces.

## Test method

The focused web contract reads the generated classpath sprite, scans every emitted `<symbol>`, and checks the five presentation attributes on each symbol. It checks the deployable generated artifact rather than generator source text.

## Hand-derived expected result

Lucide 1.27.0 line icons use `fill="none"`, `stroke="currentColor"`, `stroke-width="2"`, `stroke-linecap="round"`, and `stroke-linejoin="round"` on their SVG root. Each selected generated symbol must preserve those values.

## External-test boundaries

The deterministic asset contract proves the generated sprite carries theme-aware Lucide presentation attributes. It does not replace the taskmaster-owned integrated browser/detector pass for rendered layout and interactive states.
