/**
|
|
* Widget Presets Registry - v0.003.002
|
|
* Core presets come from shared widget-presets.json; autonomous modules
|
|
* (MODULE-CONTRACT v1, ADR-165-P) contribute their own presets via
|
|
* `frontend.preset_fragment` in their manifest, merged in at load time — the
|
|
* backend half of seam #3, mirroring the frontend's fragment glob-merge.
|
|
*
|
|
* To add a core widget:
|
|
* 1. Edit /shared/widget-presets.json
|
|
* 2. Both frontend and backend will use the new preset automatically
|
|
*
|
|
* A module widget lives ONLY in its module's presets.fragment.json — remove the
|
|
* module dirs and the preset disappears from both trees, no core edit.
