JS: FpSimpleRecipeEditor component reads recipe_id from
props.action.context (matches the existing tree editor's contract).
HTML5 native drag-drop between Library (right) and Selected (left)
panels — uses two distinct dataTransfer types (application/x-fp-step
vs application/x-fp-library) so the drop handler knows whether to
reorder or snapshot-copy.
XML: 2-column grid layout. Selected has per-row × remove (hover
reveal), drag handle, position number, icon, name, station-count
badge. Library has search input, scrollable item list with empty-
state, drag-handle items.
SCSS: tokens follow the fp_shopfloor pattern with dark-mode SCSS @if
branch (CLAUDE.md rule). 2-fr grid that collapses to single column
under 900px for tablet/mobile.
Tag: fp_simple_recipe_editor — registered via registry.category('actions').
