Shrikhand typography. off-white paper with a full pastel sticky-note palette (yellow, blue, pink, gree. Best for brainstorm / workshop, creative agency credentials, design-thinking session. AI-ready design system. The sticky note is one of design's happiest accidents. Spencer Silver's failed superglue became Art Fry's bookmark, and by the mid-1980s every brainstorm wall in every agency looked like a Mondrian made of pastel squares. The physical act of scribbling on a Post-it — fast, impermanent, deliberately rough — gave teams permission to think badly before thinking well. Ideas didn't need to be precious when they cost three cents and could be crumpled in a fist. Digital tools spent years trying to replicate that energy and mostly failed. Miro boards and FigJam canvases feel clinical — too aligned, too pixel-perfect. What makes a real brainstorm wall work is the chaos: cards at odd angles, overlapping edges, handwriting that ranges from legible to hieroglyphic. Scatterbrain leans into that disorder on purpose. The Caveat typeface is the linchpin here. Its wobbly baseline and uneven letter spacing read as human thought captured mid-flight, not a font pretending to be handwriting. Pair it with slight card rotations — two to five degrees, never uniform — and you get a layout that feels like someone actually used it, not just designed it. - Density: 8/10 — Dense - Variance: 2/10 — Structured - Motion: 4/10 — Subtle - **Style:** Brainstorm, Sticky-Note, Handwritten, Playful - **Keywords:** Post-it sticky notes, Caveat, rotated cards, pastel, brainstorm, workshop, playful, warm - **Era:** 2020s Modern - **Light/Dark:** ✓ Full / ✗ None ## Colors - **Yellow** (#FFE066) — Primary surface or dominant color - **Blue** (#A5D8FF) — Accent highlight, links and focus states - **Pink** (#FFC9C9) — Secondary accent - **Green** (#B2F2BB) — Accent color, emphasis elements - **Orange** (#FFCC80) — Extended palette, decorative use - **Purple** (#D0BFFF) — Background alternate - **Paper** (#F7F5F0) — Muted text / borders - **Ink** (#2D2A26) — Extended palette ## Typography - **Display / Hero:** Shrikhand — Weight 700, tight tracking, used for headline impact - **Body:** Zilla Slab — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** Zilla Slab — 0.875rem, weight 500, slight letter-spacing - **Monospace:** JetBrains Mono — Used for code, metadata, and technical values Scale: - Hero: clamp(2.5rem, 5vw, 4rem) - H1: 2.25rem - H2: 1.5rem - Body: 1rem / 1.6 - Small: 0.875rem ## Layout - **Grid:** CSS Grid primary.
