Presets (p)

p:{name} renders a named preset — a rendition whose definition (size, fit, quality, smart-crop behavior) is managed per brand on the server. The URL stays stable while the definition can be retuned; edits purge the edge cache so embeds pick up the new look without changing a single URL.

Presets are mutually exclusive with w and c: a preset owns its geometry and quality. You can still override delivery knobs — an explicit q: or dpr: on top of a preset wins.

Ask your Brandcenter admin (or the plugin picker) which presets your brand defines — unknown preset names are rejected against the live registry.
