Now let me read the key shadcn components I'll use:

Now let me also check the button, tabs, and separator components:

The questionnaire comparison dashboard is built. I adapted the existing comparison table layout from your screenshot to handle long-form questionnaire answers by: (1) organizing all 9 RFP sections (Vendor Info, Service Delivery, SLAs, Biotech Experience, etc.) as collapsible accordion rows matching the existing UI pattern, (2) showing truncated 2-line previews in each supplier column cell, and (3) opening a right-side Sheet panel when you click any cell to read the full answers from both suppliers side-by-side. The data model in lib/questionnaire-data.ts contains the complete question structure from the SAP ByD AMS RFP plus realistic paragraph-length mock answers for both "EleganceCraft Components" and "Aurum Forge".
