+- Added `odyssey_product_picker` component — a form-integrated product selector with "All" / "Specific" toggle and per-product checkboxes. Expects products as `%{id, name, color}` atom-keyed maps. Auto-extracts `selected_ids` from the form field value (supports maps, structs, and Ecto changesets) when not explicitly provided.
+- Added `OdysseyProductPicker` JS hook for client-side checkbox ↔ hidden field sync.
+- Added `odyssey_select` component — a generic dropdown LiveComponent with search/filter.
+- Added product picker and select demos to the showcase app with LiveView tests.
