# Illustration: Outlined cartoon

A cheerful character illustration: one big-headed person in a lively pose, acting on one large hero prop, every shape flat-filled and ringed with hand-inked near-black line. It suits friendly product moments (success, onboarding, empty states) where a face and a gesture carry the message.
Use `illustration-bold-pop` instead for a dense, saturated object cluster with navy extrusions and hatching; `illustration-flat` when you want no outlines at all; `illustration-line-interior` for thin single-weight line, mostly white fills and realistic slim people in a wide room.

Extracted from a set of 42 original design-and-coding cards in 14 styles; the three cards in examples/ are this style's shipped cards.

## The look in one sentence
Every flat-filled shape sits inside a warm near-black ink line that varies by role (2.5 px silhouettes, 2 px parts, 1.5 px details), and every interior mark (folds, brows, finger and hair splits, white highlights) is a tapered sliver that swells in the middle and ends in two points, so the drawing reads as inked by hand, never as a uniform marker line.

## Palette
Measured from the three examples. Flat fills only.

| Role | Hex | Where it goes |
|---|---|---|
| Ink | `#1e1b1b` | every outline, pupils, brows, folds, code tokens, decor strokes. Never `#000` |
| White | `#ffffff` | eye whites, sneaker soles and toe caps, socks, screens, cards, highlight dashes, check ticks |
| Periwinkle / shade | `#6b7fd4` / `#4c5fb6` | hoodies, trousers, laptops, card headers, sneakers; shade only as fold slivers |
| Periwinkle pale / glass | `#c4ccf0` / `#dfe4f8` | secondary UI bars; lens glass tint (at fill-opacity 0.22) |
| Tomato red / shade | `#e5281d` / `#a9180f` | hair, tees, sneakers, trophy base, comment bubbles, grips |
| Warm yellow / shade | `#f6c343` / `#d99a1e` | trousers, trophies, blond hair, rims, poles, avatar dots |
| Leaf green / shade / light | `#4ea54a` / `#2f7f2c` / `#7cc777` | check badges, success buttons, paint |
| Blush pink / shade / light | `#f6a3b6` / `#dc7393` / `#fde0e5` | sweaters, avatar dots, tape, diff highlight rows |
| Skin salmon (+ crease, blush) | `#f5a39c` (`#d97e77`, `#ec7d78`) | light skin, cool |
| Skin peach (+ crease, blush) | `#fbd2c0` (`#e39c86`, `#f2898a`) | light skin, warm |
| Skin brown (+ crease, blush) | `#c97a5a` (`#9c5238`, `#e0625a`) | brown skin |
| Mouth / tongue | `#8a1b1b` / `#ec7d78` | open mouth fill, tongue |
| Dark hair | `#2b2525` | black hair (red `#e5281d` and yellow `#f6c343` hair are the other two) |
| Greys | `#b9b4c4`, `#d6d2df`, `#c9c6d6`, `#e6e3ee` | gutter dashes and label lines, dividers, shading on white garments, metal wire |
| Row tint | `#e3f2df` | approved/added rows in a code card |

The pencil wood `#f3d9a8` in Designer is the one deliberate off-palette tint; `lint --palette` warns on it.

- No background: the card is transparent and the page supplies white. No gradients, patterns, filters, opacity tricks or textures (the one exception is the 0.22 glass tint).
- Shade colours appear only as fold slivers or one small shadow band, never as big flat shadow shapes.
- One saturated colour per garment; give the hero prop a colour the clothes don't already use heavily (yellow trophy against a blue hoodie, green button against a red tee).

## Line and fill
All widths are final card px at 480 wide.
- **Outlines are strokes** on the filled shape, `stroke="#1e1b1b"`, `stroke-linejoin="round" stroke-linecap="round"`.
  - 2.5 px (`WO`): head, hair, torso, sleeves, trousers, shoes, the hero prop's silhouette.
  - 2.0 px (`W`): hands, cuffs, collars, necks, ears, small prop parts.
  - 1.5 px (`WI`): eye whites, screen insets, small inner panels. Fingers and thumbs 1.7–1.8.
  - Decor is unscaled: big "+" 2.0, small "+" 1.7 and 1.6, rings and squares 1.7, check badge 1.9, emphasis ticks 1.8.
- **Union outlines:** shapes of one colour that join (torso + both sleeves, pelvis + front leg, palm + forearm) share ONE outline: ink copies stroked at 2× the width underneath, then the fills on top (`union()` in the kit). Separate outlines at a join read as a seam.
- **Folds are filled slivers, not strokes:** `fold(points, w)` swells to `w` and tapers to 0.35 px at both ends.
  - Clothing folds 1.3–1.9 px in ink or the garment's shade colour; brows 4.0 / 3.6; upper eyelid 2.0; nose hook 1.8; hair splits 1.4–1.5; finger splits 1.15; white highlight dashes 1.8–2.4.
  - Rib bands (hems, cuffs): vertical shade-colour slivers every 8 units, 1.3 px.
- Rods, cords and wires: an ink stroke 2×outline wider underneath, the colour stroke on top (`tubeStroke`).
- The scene is drawn in local units and scaled by 0.84 (`compose()`), so a stroke written as 2.5 appears in the file as 2.98. Never scale a group without dividing its stroke widths, or the weights drift.

## Characters
- **Proportions:** head with hair is about 37 % of standing height (code-review figure: hair top to sole 227 px, hair top to chin 85 px). Face 45 × 52 px. Short torso, short legs, round soft limbs.
- **Head:** a soft rounded box (`head()` in the kit), 3/4 turned toward the action, ears as 5 × 7.2 ellipses with an inner fold, a neck that narrows into the collar.
- **Eyes:** big white ellipses (near 6.2 × 7.4, far 5.4 × 7.0 local units), ink pupil r 3.7 / 3.4 with a white highlight r 1.25 up-right, a heavy upper-lid sliver 2.0. Glasses, when worn, are ink rings r 10 at 2 px.
- **Brows:** thick, tapered, 4.0 and 3.6 px. Thin brows were a judge note on the first card.
- **Mouth:** open, dark red fill with a tongue, outlined 1.9; a grin adds a white top-teeth band. Pink blush ellipses (4.8 × 2.8) under each eye, no outline.
- **Hair:** a scalloped blob (arcs between points, `hair()`), 2.5 outline, 2–3 white highlight dashes plus one white dot, and 3–5 split slivers in ink or the hair's shade. Buns and pencils behind the ear are hair accessories.
- **Hands** (follow references/craft.md for handedness, then check here):
  - Built cuff → tapered forearm (12 → 10 local units) → palm unioned into the forearm (no wrist seam) → a finger band → a thumb.
  - Fingers are one band with scalloped knuckle bumps; separations are short ink slivers (1.15 px) running in from the knuckle edge, 2.5–2.8 units long. Never separate sausage fingers, never stripes.
  - The thumb's root has no outline across it: only its two sides and tip are inked, so it grows out of the palm.
  - Hand length about 0.6 × face width. `fist()` in the kit draws both grip views and returns which hand it is.
  - Holding a flat object (laptop, tray): palm up under the base, finger band along the underside, thumb hooked over the front lip. A laptop balanced on fingertips was the first card's main fault.
  - Two hands on one handle: the near shoulder is the back one, so the NEAR hand takes the grip nearer the body and the FAR hand the grip further along. Keep fist centres at least 40 local units apart (a fist is about 28 wide plus its thumb) so a stretch of handle shows between them.
  - Reach: two 36-unit bones reach 72 local units. Place each wrist first, within reach of its shoulder, then get the grip centre with `gripFromWrist()`. Pick `elbow()`'s side so the elbow bends down and outward (below the shoulder-to-wrist line for a low grip); an elbow bending upward reads as a broken arm.
- **Feet:** chunky sneakers about 40 local units long (`shoe()`): white sole 2.5, coloured upper 2.5, white toe cap, two white lace ticks, optional white ankle eyelet, one shade sliver at the heel; ankle socks (white or light pink) and rolled hems (23 units wide with one shade sliver).
- **Clothing:** hoodie (kangaroo pocket, white strings, hood band), sweater with rib hem and crew neck over collar points, tee, dungarees with bib, straps and yellow buttons. Folds at elbows, knees, crotch and the shaded side.
- **Poses that worked:** a leap with one fist raised (Awards), a lunge leaning 14° into a magnifier with both hands on the handle (Code Review), a braced push leaning back 5° on a long pole (Designer). Rotate the upper body as a group about the hip to lean; bend the knees; never stand bolt upright.

## Decor and props
- **One hero prop**, big: 35–50 % of the group's width (PR card 145 × 200 px, button pill 197 × 54 px, trophy 50 × 90 px). It carries the subject. Small UI inside it is abstract: rounded ink or colour bars (5.6 px ink lines, 4.4 px colour bars with a 1.15 outline), gutter dashes in `#b9b4c4`, check badges, avatar dots.
- **Decor set per card (7–9 marks):** one sparkle cluster (big "+" 17 px across at 2.0, small ones at (+16, −13) and (+15, +14) sized 6.8 and 5.6), 2–3 outline rings r 4.4–4.6, three filled dots (yellow r 3.6, blue r 3.4, red r 5.2–5.4), one outline square 10 × 10 rx 1.5 rotated 18°, optional green check badge r 7.6, optional three emphasis ticks at the action point.
- Put the sparkle cluster in the top corner opposite the heaviest mass; scatter the rest in the empty corners, 15–40 px clear of any contour.
- Never: ground lines, cast shadows, clouds, plants, background panels, speech text longer than two words.

## Composition
- Transparent 480 × 360 card. Whole group (figure, prop, decor) inside x 70–430, y 40–310: margins 40–48 px top, 50–58 px bottom, at least 50 px each side.
- Figure height 230–260 px standing (65–72 % of the card), about 200 px in a deep crouch. Figure on one side, hero prop on the other, joined by the action (the magnifier, the roller pole); the prop may overlap the figure's reach but not the face.
- Feet share one implicit baseline; no line is drawn.
- Group structure the examples use: `<g id="xx-card"><g id="xx-card-decor">…</g><g id="xx-card-scene" transform="translate(TX TY) scale(0.84)">…</g></g>` (`compose()`).

## Techniques
The kit `scripts/outline-kit.mjs` holds every repeated mark. Run its self-test from the skill folder: `node scripts/outline-kit.mjs demo.svg` (add `--proof` to paint thumbs red and index fingers blue).

```js
import * as K from '/abs/path/to/illustration-outlined-cartoon/scripts/outline-kit.mjs';
const { C, SKIN, W, WO, fold, limb, union, path, head, hair, dash, fist, shoe, hem, compose } = K;
// a tapered sleeve unioned with the torso: one silhouette, no seam
const arm = limb([[220, 178], [199, 190], [180, 200]], [24, 22, 19], 'round', 'flat');
scene.push(union([K.TORSO, arm], C.blue, WO));
// a fold: swells to 1.5 px, pointed ends
scene.push(fold([[187, 192], [181, 193.6], [175, 191.5]], 1.5));
```

A fist on a rod (`fist()`): decide the hand from the arm first, then read `hand` back and compare.
```js
const v = K.unit(handleEnd, malletHead);         // along the handle, toward the business end
const wrist = K.at(shoulderN, [0.79, 0.62], 66); // wrists first, within 72 of the shoulder
const c = K.gripFromWrist(wrist, v, shoulderN);
const e = K.elbow(shoulderN, wrist, 36, 36, 1);  // side chosen so the elbow drops
const cuff = K.lerp(e, wrist, 0.42);
const h = fist({ c, v, elbow: e, from: cuff, rr: 5, view: 'back', ...SKIN.brown });
if (h.hand !== 'right') throw new Error('near arm of a figure facing right is the RIGHT hand');
scene.push(h.behind, sleeve, rod, h.front, cuffBand);   // the cuff band goes last: in the back view the forearm is in `front`
```
`view: 'palm'` puts the curled fingers across the front of the rod with the thumb over the index; `view: 'back'` shows the back of the hand with a knuckle row and the thumb wrapping the business end. Thumb and index always sit toward `v`.

Union outline by hand, when you don't use the kit:
```xml
<path d="M…torso…" fill="#1e1b1b" stroke="#1e1b1b" stroke-width="5" stroke-linejoin="round"/>
<path d="M…sleeve…" fill="#1e1b1b" stroke="#1e1b1b" stroke-width="5" stroke-linejoin="round"/>
<path d="M…torso…" fill="#6b7fd4"/><path d="M…sleeve…" fill="#6b7fd4"/>
```

## Failure modes
- **Line reads as a uniform marker.** Every interior mark was a round-capped stroke of one width. Use `fold()` slivers and the three outline weights.
- **Weak, generic face.** Brows were thin lines; draw them as 3.6–4.0 px tapered slivers with a heavy upper lid.
- **Decor reads as noise.** Marks were sprinkled evenly. Group them: one sparkle cluster, then a few rings, dots and one square in the empty corners.
- **Prop balanced on fingertips.** A laptop sat on the fingertips; hold flat objects from below with the thumb over the lip.
- **Thumb on the wrong side.** A designer rejected a whole pass of hands for this. Decide left/right and palm/back per craft.md, use `fist()` and check its `hand`, then render a `--proof`-style copy at 8×.
- **Mitten or pasted-on fist.** No forearm taper, no wrist, no finger splits. Build cuff → forearm → palm → finger band → thumb.
- **Seam lines where parts join.** Sleeves outlined separately from the torso. Union same-colour shapes.
- **Knee notches.** Two separate trouser tubes overlapping at the crotch. Union the pelvis with the front leg; outline the back leg on its own behind it.
- **Weights drift after scaling.** A group was scaled without dividing its stroke widths. Use `compose()` or divide by the scale.
- **Thumb root outlined across the palm.** A closed thumb shape drew a seam over the hand; ink only its sides (`fist()` does this).
- **Elbow bends upward.** `elbow()` was given the wrong side; the arm read as broken. Flip `side` until the elbow drops.
- **Two fists merge into one blob.** Grip centres 30 units apart; the handle vanished between them. Keep 40+.
- **Arms can't reach, hands float.** Grip points chosen from the prop, then arms stretched to them. Place wrists from the shoulders first.
- **Hidden subject.** A squashed bug drawn under a mallet head vanished at 1x. Let anything pinned under a prop poke out at least 40 % on the open side, away from feet and other contours.
- **Decor lost or stray.** Decor is drawn first, under the scene, so a dot placed under a prop disappears; emphasis ticks fanned onto a prop read as stray scratches. Check each mark is in clear space.

## Examples
- `examples/awards.svg`: leaping figure in hoodie and glasses, laptop held palm-up from below, trophy raised in a fist; front-facing head, red blob hair, motion ticks under the jump.
- `examples/code-review.svg`: brown-skinned figure lunging with a magnifier held in two fists, a big PR card with diff rows, check badges and a red comment bubble; the lens magnifies the card under a clip path.
- `examples/designer.svg`: blond figure with bun and pencil braced against a long roller pole painting a green "Sign up" button, dashed outline for the unpainted part, drips, paint tray and taped swatches; two grip views on one pole.

## Workflow
Commands run from the skill folder (Playwright must resolve: `npm i -D playwright-core` there or globally).
1. **Brief:** name the subject and the one gesture that shows it. Pick the hero prop and what it shows at 1x.
2. **Pose:** decide the lean, which arm is near, where each hand grips. For each hand write down LEFT/RIGHT, PALM/BACK, finger direction (references/craft.md).
3. **Block:** write a generator next to your card (`card.gen.mjs`) that imports the kit by absolute path. Place the prop first, then the hip pivot, ground y and shoulders, then wrists within reach, grips (`gripFromWrist()`), elbows (`elbow()`), ankles. Print the key points and the `hand` of each fist.
4. **Draw** back to front: far arm, legs and shoes, torso group (rotated about the hip), head, prop, near arm, hands, then decor in card px. `compose({ id: 'xx-subject', label, decor, scene, TX, TY })`.
5. **Render:** `node scripts/render.mjs card.svg card.png`.
6. **Sheet:** `node scripts/render.mjs --sheet sheet.png examples/*.svg card.svg`. Ask "same hand, same set?".
7. **Zoom:** `node scripts/render.mjs card.svg z-hand.png --zoom x,y,w,h --scale 8` for every hand, the face, both shoes and every contact. Make a thumb-proof copy (`fist({ …, proof: true })`) and zoom it.
8. **Critique** against the five criteria in references/craft.md, harshly. Fix and re-render. Expect 3–4 rounds.
9. **Lint:** `node scripts/lint.mjs card.svg --prefix xx- --palette style.json`. Only deliberate one-offs may warn.

## Verify
- [ ] Every filled shape has an ink `#1e1b1b` outline; no shape is outline-only except decor rings, the square and dashed guides.
- [ ] Three outline weights are visible: silhouettes heavier than hands, hands heavier than eye whites.
- [ ] Folds, brows, hair splits and finger splits are tapered slivers with pointed ends (zoom 8× on one).
- [ ] Brows are thick (3.6–4 px) and the eyes are white ellipses with a pupil and a white highlight.
- [ ] Pink blush ellipses with no outline sit under the eyes; the mouth is open with a tongue.
- [ ] Hair is a scalloped blob with at least two white highlight dashes.
- [ ] Each hand: cuff, tapering forearm, palm, finger band with short splits, thumb on the side craft.md requires (proof render checked).
- [ ] Same-colour joins (sleeve to torso, pelvis to leg) show no seam line.
- [ ] Sneakers have a white sole and toe cap; trousers end in rolled hems.
- [ ] Exactly one sparkle cluster (big + two small); 7–9 decor marks in total, none touching a contour or hidden under a prop.
- [ ] No ground line, shadow, gradient, texture or background rect.
- [ ] Group inside x 70–430, y 40–310; figure 230–260 px tall; the subject reads at 1x.
- [ ] `lint.mjs --palette style.json` passes with only deliberate warnings.
