| 1 | # Visual style: chalkboard |
| 2 | |
| 3 | 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. |

| 7 | ## 1. Shape & decoration |
| 8 | |
| 9 | - 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. |
| 10 | - 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. |
| 11 | - Decoration: underlines and emphasis marks; a few sprinkled chalk stars / dots. Blackboard pedagogy — organized sections, a clear central focus. |
| 12 | - Whitespace: the dark board reads as room; let chalk marks breathe rather than crowd. |
| 13 | |
| 14 | ## 2. Typography character |
| 15 | |
| 16 | - Hand-lettered chalk character for titles; legible body. Dry, nostalgic, classroom-warm. |
| 17 | |
| 18 | > Families are chosen at confirmation `g`; this style asks for a hand-lettered chalk title *character*. |
| 19 | |
| 20 | ## 3. Using the deck's colors |
| 21 | |
| 22 | - Dark slate field; off-white chalk carries most marks; the deck's colors appear as soft, powdery pastel chalk accents, used sparingly. |
| 23 | - Restrained and powdery — never saturated fills. |
| 24 | |
| 25 | > HEX values come from confirmation `e`; this style only governs the chalk-on-slate, powdery-accent discipline — it names no colors. |
| 26 | |
| 27 | ## 4. Texture / elevation |
| 28 | |
| 29 | - Flat — depth from chalk-stroke weight, not material. Chalk-dust grain texture across the board is on-brand; no drop shadows. |
| 30 | |
| 31 | ## 5. Paired image-rendering |
| 32 | |
| 33 | `chalkboard` — chalk-on-slate imagery with the same classroom feel. |
| 34 | |
| 35 | ## 6. Illustration propensity |
| 36 | |
| 37 | **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. |
