Style System

Core Look

High-end editorial PPT design with Japanese hand-drawn illustration. The deck should feel like a quiet Japanese lifestyle magazine page: human, calm, textured, imperfect, and refined.

Canvas

• Aspect ratio: 16:9
• Default SVG viewBox: 0 0 1280 720
• Background: #F8F6F2
• Safe margin: 80 px minimum
• Preferred content width: 980-1080 px
• Texture: subtle grain, sparse speckles, faint paper fibers

Palette

• Warm White: #F8F6F2
• Ink Black: #2B2B2B
• Soft Gray: #BDBDBD
• Muted Indigo: #6C7A89
• Pale Wash: #EAE7E1

Use ink black at softened opacity when possible. Muted indigo is a quiet accent only. Pale wash is for very soft background fills.

Typography

Use clean Japanese-style sans-serif typography.

• Preferred fonts: Noto Sans JP, Yu Gothic, Yu Gothic UI, Hiragino Sans, Microsoft JhengHei, Microsoft YaHei, Arial, sans-serif.
• Cover title: 52-68 px, 300-500 weight.
• Slide title: 34-46 px, 300-500 weight.
• Section label: 11-13 px, 400-500 weight.
• Body: 18-23 px, 300-400 weight.
• Caption and annotation: 12-15 px, 300-400 weight.
• Line height: 1.35-1.65.
• Letter spacing: 0.02em max; keep it subtle.

Avoid heavy bold headings. Use space, alignment, and line breaks for hierarchy.

Layout Rules

• Use asymmetric editorial composition.
• Do not center text and illustration together.
• Let one side breathe.
• Keep illustration and text in a quiet conversation.
• Use thin dividers and tiny annotations rather than framed cards.
• Leave generous margins around hand-drawn visuals.

Illustration Rules

Illustrations should look hand-drawn, not like polished vector icons.

• Subjects: daily life, workspace, creative process, human-centered ideas, quiet abstract concepts.
• Line style: thin, uneven, organic, slightly imperfect.
• Fill style: very light watercolor wash.
• Details: sparse annotations, small arrows, tiny labels.
• Texture: paper grain and pencil softness are welcome.
• Composition: delicate visual cluster, not full-canvas busy scene.

Graphic Elements

• Hand-drawn lines
• Small note marks
• Minimal dividers
• Soft wash blocks
• Gentle irregular strokes

Avoid sharp geometric tech elements, bright dashboards, neon accents, 3D objects, and glossy UI cards.

Data And Diagrams

If data or systems must be shown, translate them into soft editorial diagrams:

• Use hand-drawn arrows and imperfect connector lines.
• Use small annotations instead of dense labels.
• Use pale wash areas for grouping.
• Keep chart density low.
