CSS Font Weight Normalizer

Build a tool that normalizes CSS stylesheets by converting font-weight keyword values to their numeric equivalents.

Requirements

Your tool should process CSS input and convert font-weight values according to standard CSS specifications:

• Convert keyword values to their numeric equivalents
• Preserve other CSS properties unchanged
• Return the processed CSS as a string

The tool should handle:

• CSS provided as strings
• Multiple rulesets in a single stylesheet
• Mixed keyword and numeric font-weight values
• Other CSS properties that should remain unchanged

Test Cases

• Given CSS with font-weight: normal, it converts to font-weight: 400 @test
• Given CSS with font-weight: bold, it converts to font-weight: 700 @test
• Given CSS with multiple rulesets containing various font-weight keywords, it converts all keywords to numeric values @test
• Given CSS with numeric font-weight values already present, it preserves them unchanged @test
