What is a content slot in B2C Commerce and how does it differ from a content asset?

These two concepts are often confused but serve distinct purposes:

1. Content asset — a standalone piece of managed HTML content (banner, legal text, promotional copy) created and edited in Business Manager under Merchant Tools > Content > Content Assets. A content asset is static until a merchandiser edits it. It is rendered by including it in a template using <iscontentasset> or via a content slot.
2. Content slot — a named placeholder defined in an ISML template. Merchandisers configure what appears in each slot via campaign-controlled slot configurations in Business Manager. The same template location can show different content to different customer groups or during different date ranges without any code change.

The key distinction: content assets are "what" to show; content slots are "where and when" to show it. Content slots enable personalisation and campaign scheduling on top of content assets (or product recommendations).
