Why namespaced shortcodes?

All shortcodes in this module are namespaced under dx/ (for example: dx/photo, dx/code).

Hugo does not provide automatic isolation between shortcodes coming from different themes or modules. If two themes or modules define a shortcode with the same name (for example code or photo), whichever one Hugo resolves first will “win” — often leading to confusing or hard-to-debug behavior.

Namespacing solves this by:

Avoiding collisions with themes like Blowfish (which already defines code)
Making ownership explicit
Allowing safe composition of multiple Hugo modules
Future-proofing the API as the module grows

If you prefer shorter aliases for a specific site, you can create local wrapper shortcodes that delegate to the dx/* versions.
