Jim Liu 宝玉 4bd5fe573e feat(baoyu-article-illustrator): default to sketch-notes educational infographic style
Make `hand-drawn-edu` (infographic + sketch-notes + macaron) the universal
fallback preset when content analysis surfaces no strong signal. Rework
sketch-notes style spec around warm cream paper + black hand-drawn lines +
soft pastel section blocks.

- Change `hand-drawn-edu` preset type from flowchart to infographic; add
  `hand-drawn-edu-flow` (flowchart) and `hand-drawn-edu-compare` (comparison)
  as variants for users who need those layouts in the same warm style
- Elevate `sketch-notes` to primary style across infographic / flowchart /
  comparison / framework auto-selection; add sketch-notes column to
  Type x Style compatibility matrix
- Rewrite sketch-notes.md: macaron pastel palette, canonical single-page
  layout (title / sectioned boxes / takeaway), diagram-only rule
- Add infographic + sketch-notes + macaron prompt block to
  prompt-construction.md
- Update workflow, style-presets, and first-time-setup defaults to match

sketch-notes

Hand-drawn educational infographic style with warm cream paper, black hand-drawn lines, and soft pastel section blocks. Optimized for single-page visual explainers.

Design Aesthetic

Hand-drawn educational infographic in a clean presentation style. Feels like a visual explainer slide: simple, friendly, and easy to understand at a glance. Bold handwritten-style title at the top, clearly sectioned content in the middle with rounded boxes and small doodles, and one short takeaway sentence at the bottom. Neat, airy, and visually similar to a hand-drawn concept diagram — never realistic or photographic.

Background

  • Color: Warm Cream Paper (#F5F0E8) — preferred; fallback Warm Off-White (#FAF8F0)
  • Texture: Subtle warm paper grain, matte finish, no gloss

Color Palette

Default sketch-notes palette is the macaron pastel set. Lines are always black; pastel blocks are used only as rounded card fills for information sections.

Role Color Hex Usage
Background Warm Cream #F5F0E8 Paper background
Primary Ink Black #1A1A1A ALL outlines, text, arrows, doodles
Block Blue Light Blue #A8D8EA Info block fill (cool / tech)
Block Mint Mint Green #B5E5CF Info block fill (growth / positive)
Block Lavender Lavender #D5C6E0 Info block fill (concept / abstract)
Block Peach Peach #FFD5C2 Info block fill (warm / human)
Accent Coral Red #E8655A One or two emphasis points only
Muted Text Warm Gray #6B6B6B Small annotations

Use 4 pastel block colors max per image, one color per section. Black ink does all the structural line work.

Visual Elements

  • Bold hand-lettered title at the top (oversized, slightly wobbly)
  • Rounded-rectangle info boxes with clear sectioning (26 zones)
  • Short keyword labels inside boxes — never long paragraphs
  • Simple icons and sketchy cartoon elements (stick figures, tools, objects) to explain each idea
  • Hand-drawn arrows (straight, curved, or wavy) connecting related zones
  • Small doodle decorations: stars, sparkles, underlines, dots, asterisks — used sparingly for emphasis
  • Single-line hand-lettered takeaway sentence at the bottom
  • Color fills do not completely fill outlines (slight "hand-painted" overshoot/undershoot)
  • Generous white space between sections — airy, never crowded

Layout Guidelines

Canonical single-page layout (16:9 or 4:3):

  1. Top (1015%) — Bold hand-lettered title, optionally with a small decorative underline or doodle.
  2. Middle (7080%) — 26 rounded pastel info boxes arranged in a clear grid, row, or radial pattern. Each box = one section, one color, one icon, one keyword/phrase.
  3. Bottom (1015%) — One short hand-lettered takeaway sentence summarizing the core insight.

Keep margins generous. Aim for breathing room around every element.

Style Rules

Do

  • Use warm cream paper background (no pure white)
  • Use black hand-drawn lines for ALL structural elements
  • Use soft pastel blocks (blue / mint / lavender / peach) for section fills
  • Keep text to short keywords and phrases only
  • Include a bold handwritten title at the top
  • Include a short takeaway sentence at the bottom
  • Use diagram-style visuals (icons, doodles, simple shapes)
  • Allow slight wobble — hand-drawn imperfection is the point
  • Maintain clear sectioning with rounded boxes

Don't

  • Use pure white backgrounds (that's ink-notes' territory)
  • Render realistic or photographic images — this style is diagram-only
  • Fill zones with gradients, shadows, or digital effects
  • Use long paragraphs of text — keywords only
  • Use computer-generated / sans-serif body fonts — ALL text must be hand-lettered
  • Use more than 4 pastel block colors per image
  • Overcrowd the canvas — keep it airy and minimal
  • Use perfect geometric shapes — preserve the hand-drawn wobble

Type Compatibility

Type Rating Notes
infographic ✓✓ Best fit — single-page visual explainers, concept summaries, educational slides
framework ✓✓ Labeled zones and connectors render well
flowchart ✓✓ Rounded step boxes with wavy arrows
comparison ✓✓ Two pastel blocks side by side; prefer ink-notes for strict Before/After contrasts
timeline Hand-drawn horizontal arrow with milestone cards
scene Not recommended — too diagrammatic

Best For

Educational content, knowledge sharing, concept explainers, tutorials, onboarding materials, product walkthroughs, single-page visual summaries, "how things work" posts, friendly technical articles
