Overview

‘data-<ctrl>-<name>-class` fragment — a named CSS class set readable on the JS side as `this.<name>Class`. Renamed from v1’s ‘StimulusClass` (which collided with Ruby’s ‘Class` — uncomfortable to type in user code).

‘css` holds the final serialised string form (space-joined); the parser normalises String / Array-of-String / Array-of-anything inputs down to one shape so the Draft/Plan doesn’t have to care.
