One card per concept, kept deliberately brief. They are records of the third content archetype: no dates, ordered by hand, dragged into place in the panel — where the other two order themselves by a publication date and by an event date.
One class per model. Declares the fields; the panel builds the index, the editor, validation, search and filters from them.
One field, declared fluently. The input type and every rule about it hang off the same call.
A block of page content, stored as json. Declared once with its own fields, rendered by a Blade view of the same name.
One record per file, attached to as many models as you like. Crop, focus point and alt text per language live on the record.
A model registered in one place, after which the search, the sitemap, the page editor and the structured data all know about it.
Permissions per module and per action. Without read on a module it is not in the menu and its URL is a 404.
Three of them, each off until you name a provider, and each free to use a different one.
A bar, not a wall. Categories are allowed separately and third-party snippets stay parked until theirs is.
