withAccordionTemplates

Description#

Set app-wide slot templates - the config tier of the slot cascade (*cngxAccordionItemXxx per-instance -> this -> CSS default). Three slots carry a config tier: icon (chevron; $implicit is the item's expanded state), busySpinner (loading/refreshing visual), and error (error affordance). Hand a TemplateRef per key here and every item renders it unless a per-instance slot overrides it. Partial payloads compose - repeated calls merge per key.
