test: remove low-signal test files

[t3-code]

this removes eight complete test files that added maintenance cost without protecting a useful regression boundary.

removals

• deletes static-markup tests that only froze current tailwind classes and jsx structure
• deletes tests that transcribed obvious constants, one-line mappings, and generated identifier formatting
• deletes a web wrapper test that exercised the platform URL constructor through a direct re-export
• deletes a source-text dependency check that only recognized one exact import spelling

no production code changed. this removes 14 tests and 135 lines across eight files.

verification

before deletion:

• vp test run <eight removed files> passed, 8 files and 14 tests

after deletion:

• vp test run packages/client-runtime/src/state/assets.test.ts apps/web/src/components/ui/button.test.tsx passed, 2 files and 7 tests
• affected web, mobile, server, and shared package typechecks passed
• server typecheck emitted only existing ts377019 suggestion diagnostics
• git diff --cached --check passed
• all 1,030 open pull requests were checked for path conflicts; none touches these files

Note

Low Risk
Test-only deletions with no runtime behavior changes; regression coverage drops only for previously low-signal assertions.

Overview
Removes eight entire test files (~135 lines, 14 tests) across mobile, server, web, and shared with no production code changes.

The deleted suites were mostly brittle or low-value: static React markup assertions on Tailwind/class names (StartTruncatedPath, toggle-group), trivial constant/mapping checks (mobileBranding, Attributes, themePreview), a thin URL wrapper test (assetUrls), random ID format checks (previewAutomationClientId), and a string-matching guard on main.tsx / package.json for react-grab imports.

Production helpers and components are unchanged; only test maintenance surface is reduced.

Note

Remove low-signal test files across mobile, server, web, and shared packages

Deletes 8 test files that covered pure mapping functions, simple ID generation, and structural assertions with limited regression value. Affected files span mobileBranding, Attributes normalization, assetUrls, StartTruncatedPath, previewAutomationClientId, toggle-group, reactGrabBoundary, and themePreview.

Approvability

Verdict: Approved at cdaa8fc

Macroscope's review found this PR approvable — The PR removes eight test-only files containing 14 low-signal assertions across mobile, server, web, and shared code, while leaving production sources and runtime entry points unchanged. Its only material effect is reduced regression coverage and test-maintenance surface.
