Layout parameters
Application components expose continuous values as CSS variables:
Use these parameters instead of overriding internal grid selectors.

The A3S style pack applies the same compact chrome rhythm used by A3S Office. Override these semantic tokens only when the entire product needs a different density:
Keep the 4px baseline when changing a token and validate the complete shell at desktop and compact widths.
