1. Inspect the request and determine whether you are creating a new deck, recreating an existing deck, or editing one.
2. Set the slide size up front. Default to 16:9 (`LAYOUT_WIDE`) unless the source material clearly uses another aspect ratio.
3. Copy `assets/pptxgenjs_helpers/` into the working directory and import the helpers from there.
4. Build the deck in JavaScript with an explicit theme font, stable spacing, and editable PowerPoint-native elements when practical.
5. Run the bundled scripts from this skill directory or copy the needed ones into the task workspace. Render the result with `render_slides.py`, review the PNGs, and fix layout issues before delivery.
6. Run `slides_test.py` for overflow checks when slide edges are tight or the deck is dense.
7. Deliver the `.pptx`, the authoring `.js`, and any generated assets that are required to rebuild the deck.
