# Visual style: chalkboard

Classroom chalkboard — a dark slate field, soft chalk-stroke line work, powdery pastel accents. Nostalgic and instructional. For teaching decks, tutorials, school / academic content, retro-classroom atmosphere.

---

## 1. Shape & decoration

- Shape language: chalk-stroke line work with slightly diffused, dry-medium edges; sketched boxes, brackets, arrows in chalk. Confident but never mechanical — the sketched boxes and arrows are `<path>` with non-aligned points; a primitive `<rect>` / `<line>` snaps the chalk back to mechanical.
- Composition geometry: one big chalk ring around the term that matters; a radial mind-map spreading from a central concept; a hand-drawn arc timeline sweeping the board; an oversized chalk bracket grouping half the page; a boxed corner note holding the takeaway.
- Decoration: underlines and emphasis marks; a few sprinkled chalk stars / dots. Blackboard pedagogy — organized sections, a clear central focus.
- Whitespace: the dark board reads as room; let chalk marks breathe rather than crowd.

## 2. Typography character

- Hand-lettered chalk character for titles; legible body. Dry, nostalgic, classroom-warm.

> Families are chosen at confirmation `g`; this style asks for a hand-lettered chalk title *character*.

## 3. Using the deck's colors

- Dark slate field; off-white chalk carries most marks; the deck's colors appear as soft, powdery pastel chalk accents, used sparingly.
- Restrained and powdery — never saturated fills.

> HEX values come from confirmation `e`; this style only governs the chalk-on-slate, powdery-accent discipline — it names no colors.

## 4. Texture / elevation

- Flat — depth from chalk-stroke weight, not material. Chalk-dust grain texture across the board is on-brand; no drop shadows.

## 5. Paired image-rendering

`chalkboard` — chalk-on-slate imagery with the same classroom feel.

## 6. Illustration propensity

**core** — chalk-drawn marks and doodles are the classroom aesthetic; with no user steer, default to recommending a coherent spot-illustration family. Default *lean* only — heaviness and placement stay Strategist judgment, an explicit user request wins either way, and `image_usage: none` writes no illustration rows.
