Module: Vident::Internals::ClassListBuilder

Defined in:
lib/vident/internals/class_list_builder.rb

Overview

Builds the root element’s CSS class list with a 6-tier precedence cascade. Tiers (left-to-right): component_name, then the highest-priority non-nil of root_element_classes / root_element_attributes / root_element(class:) / html_options, then classes: prop (always appended), then stimulus class maps.
