/*
 * Filament Activity Timeline
 *
 * Only the timeline specific scaffolding lives here: the rail, the event dots,
 * the entry layout and the change chips. Everything generic (section, badges,
 * tabs, empty state, avatars) is rendered with native Filament components.
 *
 * Every color below reuses a Filament v4 core recipe, variable for variable,
 * so any custom theme flows through unchanged:
 *
 * - dots ........... the `.fi-modal-icon-bg` tinted circle recipe, scoped with
 *                    the core `.fi-color-{name}` custom properties
 * - old chip ....... the `.fi-badge` gray recipe
 * - new chip ....... the `.fi-badge` gray recipe with heading-strength text
 * - rail, panels ... the `.fi-section` hairline ring pair
 * - texts .......... the section heading and description color pairs
