Problem: When using diagrams on cards, logos placed in header/footer sections (specifically bottom-left) move from their fixed positions instead of staying locked in place as designed.

Current Setup: Header/footer is correctly configured with logo in bottom-left corner (as shown in Card headers & footers settings).

Expected Behavior: Logo should remain fixed in bottom-left corner regardless of diagram content, with diagram staying in background.

Actual Behavior: Logo shifts position and appears to interact with/be affected by diagram layout, sometimes appearing partially cut off or overlapping diagram elements.

Impact: This defeats the purpose of headers/footers as fixed positioning elements and creates unprofessional-looking presentations.

Suggested Fix: Ensure header/footer elements maintain absolute positioning and proper z-index layering so they stay locked in corners independent of card content layout.
