Remarks

Specification: CSS Font Module Level 3, Section 3.3 (font-weight)

This method implements the "lighter" keyword semantics, moving from the current weight down one step in the CSS weight hierarchy:

• 100 → Thin (100, clamped minimum)
• 200 → Thin (100)
• 300 → Thin (100)
• 400 → Light (300)
• 500 → Light (300)
• 600 → Normal (400)
• 700 → Normal (400)
• 800 → SemiBold (600)
• 900 → Bold (700)
• 950 → Bold (700)

Non-Standard Numeric: Non-standard numeric values decrement by ~100 and are rounded to the nearest standard weight.

Default: Empty or invalid input returns Normal (400).
