TSX files with many short generic arrow declarations repeatedly lexed the next 8,192 characters for every generic head. Validate complete common direct-arrow headers using a short prefix, and retain the existing 8,192-character fallback for complex or inconclusive syntax.

The focused regression tests measure lexer input for 40, 100, and 400 declarations, cover the existing lookahead boundary, and check live CSS through scan, dry-run, and removal. Independent comparison preserves all 225 previous helper decisions and all 22 previous CSS outcomes, including the existing conservative cases.

Validation: Ruff lint and format checks; all 842 tests on Python 3.10, 3.11, 3.12, and 3.13 on Linux. Offline lock/dependency checks; one wheel and sdist build, Twine, and actual private wheel installation with generated console help and scan/dry-run/removal controls.
