Core Rules

1. Widescreen 16:9 Aspect Ratio Mandate: All presentation decks must default to 16:9 widescreen ($13.333 \times 7.5\text{ in}$ / $12192000 \times 6858000\text{ EMUs}$). Standard 4:3 is permitted only upon explicit user instruction.
2. Visual Thumbnail Grid Review: Never deliver a presentation deck without rendering visual thumbnails. Run thumbnail.py deck.pptx to generate a composite grid image and inspect layout balance, contrast, and alignment.
3. Package Bookkeeping on XML Manipulation: When modifying unpacked .pptx archives:
   • Use add_slide.py to clone layouts, ensuring new slides are registered in ppt/presentation.xml (<p:sldIdLst>), ppt/_rels/presentation.xml.rels, and [Content_Types].xml.
   • Use clean.py to purge unreferenced media files and orphaned relationship files.
4. Anti-Slop Design Heuristics: Forbid cliché AI slide layouts: no uniform card grids, no purple gradients, no tiny low-contrast captions ($< 12\text{pt}$), and enforce maximum 40 words per content slide.
5. Safe Color & Typography Systems: Ground typography in distinct paired fonts (e.g. Space Grotesk + Inter) and high-contrast color palettes (APCA $L_c \ge 75$ for body text).
