 ## DONE (Completed)
+- [x] #399: Fix - Strange summary on github pages - unwanted FORD configuration appearing in documentation - FIXED: Removed YAML metadata from doc.md to fix GitHub Pages display issue, eliminating redundant project header and resolving documentation presentation problems (PR #405 merged)
 - [x] #388: Fix - investigate test_mpeg_consolidated failure unrelated to ylabel rotation (test infrastructure) - FIXED: Resolved test_mpeg_consolidated failure by properly registering animation save implementation through facade module pattern - added missing fortplot_animation import and changed from type-bound method to procedure call to ensure proper registration, now generates valid 1619-byte MPEG files with correct MP4 structure validation (PR #404 merged)
 - [x] #377: Enhancement - make finer grid on pcolormesh_demo.html - FIXED: Successfully upgraded pcolormesh demo grids from coarse to 50x50 high-resolution with comprehensive test coverage and verified visual output across PNG, PDF, and ASCII backends, enhancing mathematical function fidelity and visual quality (PR #400 merged)
 - [x] #392: Fix - Strange truncations in example documentation output - FIXED: Replaced all "[truncated]" placeholders in documentation with complete ASCII art examples using direct embedding approach following KISS principle, fixing 7 documentation files with 14+ ASCII preview sections, now showing complete plot visualization with proper axes and labels (PR #398 merged)
