/**
 * Forms — canonical, token-driven.
 *
 * Promoted from DriverReports (the fullest token-driven form styling) as the
 * canonical shared form design; every value resolves against variables.css so
 * one palette drives the whole estate. The widget blocks below the base rules
 * (buttons, disabled/readonly, dropdown-multiselect, floating labels) are kept
 * from the previous Intranet-sourced file — consumers depend on them — but
 * re-expressed as tokens rather than hardcoded colours/spacing.
