Slide Template Library (Assertion-Evidence Style)

Rule: All slide headings must be assertion sentences (complete, testable claims), not topic labels. Body content provides evidence (charts, tables, diagrams, bullet points). Keep to 3-5 bullet points maximum per slide. Place data sources in the footer (bottom-right).

Best Practices

1. Consistency: Use the same template for similar slide types throughout the deck
2. Hierarchy: Maintain consistent visual hierarchy (heading > subheading > body > footer)
3. White Space: Don't fill every pixel—leave breathing room (see STYLE-GUIDE.md)
4. One Idea: Each slide conveys exactly one testable assertion
5. Evidence-First: Body content supports the heading assertion with visuals/data, not long text
6. Accessibility: All templates must meet WCAG AA contrast requirements (see STYLE-GUIDE.md)

Next Steps: Once you've selected templates for all slides, proceed to Stage 4 (Evidence & Charts) in WORKFLOW.md.
