pub fn mark_content_dirty(ec: &mut EntityCommands<'_>)Expand description
Tap helper for EntityCommands call sites (style apply, op arms): queue a
push of this entity into LayerContentDirt. Queued (not immediate)
because the op-apply sites only hold EntityCommands; the push lands at
the next command flush, well before the PostUpdate resolver. A missing
resource (external app without the plugin) degrades to a no-op.
