Creating Slides Process
Basic Workflow

Determine target audience
Assess formality level
Select theme
Use quick selection rules above
If uncertain, consult references/theme-selection.md
Default to default theme if still unsure
Apply template
Load appropriate template from assets/
CSS is already embedded - no external files needed
Maintain template structure
Structure content
Title slide: <!-- _class: lead --> + h1
Content slides: h2 title + bullet points
Keep titles to 5-7 characters (Japanese)
Use 3-5 bullet points per slide
Refine quality
Read references/best-practices.md
Ensure adequate whitespace
Maintain consistency
Keep text concise (15-25 chars per line)
Add images
If needed, consult references/image-patterns.md
Common:  for side images
Handling "Make It Look Good" Requests
When users give vague instructions like "良い感じにして", "かっこよく", or "make it cool":
Infer theme from content:
Business content → business theme
Technical content → tech or dark theme
Creative content → gradient or colorful theme
General → default theme
Apply best practices automatically:
Shorten titles to 5-7 characters
Limit bullet points to 3-5 items
Add adequate whitespace
Use consistent structure
Enhance visual hierarchy:
Use h3 for sub-sections when appropriate
Break up dense text into multiple slides
Ensure logical flow (intro → body → conclusion)
Maintain professional tone:
Match formality to content
Use parallel structure in lists
Keep technical terms consistent
Image Integration
For slides with images, consult references/image-patterns.md for detailed syntax.
Common patterns:
Side image:  - Image on right, text on left
Centered:  - Centered with specific width
Full background:  - Full-screen background
Multiple images: Multiple ![bg] declarations
Example lecture pattern:
## Slide Title- Explanation point 1- Explanation point 2- Explanation point 3
