Scale the local inventory to 10k+ varieties: - Render the list with ListView.builder over a flattened header/item model instead of building every tile upfront. - Store a small regenerable JPEG thumbnail per photo (schema v14) and use it for the 48px list avatar; full bytes stay for offer image hosting. Existing photos are backfilled lazily at startup. Thumbnail is local-only (excluded from CRDT sync and backups by the JSON codec). - Add indexes on varieties(is_deleted,is_draft), attachments(parent_type, parent_id,kind), lots(variety_id) via @TableIndex. - Debounce watchInventoryView (~250ms) so a burst of table writes triggers one reload, not seven. - cacheWidth/cacheHeight on the list avatar decode. - Scale test raised 3k -> 10k; migration test v13 -> v14.
