Design & UX

Keep small and muted text legible by compensating weight, letter-spacing, line-height, and colour as type scales down or sits on a dark ground — ≤14px steps up a weight tier, ≤13px gets open tracking, uppercase labels get 0.08–0.12em, light-on-dark text avoids pure white and gets a weight bump. Use this whenever styling labels, captions, metadata, table cells, badges, form hints, legal/fine print, timestamps, nav links, footer text, or any text under ~0.875rem, and whenever text sits in a dar...

Start and operate the local tldraw design canvas that shows HTML artboards. Launch the dev server against a project's board folders, add or switch boards, drive shapes through the bounded window.snapCanvas bridge, and act on annotated screenshots of the canvas. Use when asked to open/launch the canvas, put a mockup on the canvas, annotate or draw on it, fix overlapping frames after a layout.json edit, or respond to a screenshot of the canvas with notes drawn on it.

Design a new screen, flow or component as a self-contained HTML artboard on the prototype canvas, built from the board's existing design tokens rather than invented values. Covers picking or extending the token block, generating a row of screens from one script, iterating against annotated screenshots, and verifying by rendering. Use when asked to mock up a new screen or feature, design variants/proposals to compare, extend an existing board with more states, or turn a spec into artboards.

Clone a real app's screens as pixel-accurate, self-contained HTML artboards on the prototype canvas. Overlay a grid on the reference and sample colours visually, derive one measured design-token block, generate one HTML file per screen from a single script, verify by re-rendering, and park the reference underneath its mockup. Use when asked to 100% copy / clone an app's UI, rebuild screens from screenshots or Mobbin, extract a design system from reference images, or check a mockup against its...

Collect a product's official brand and promotional material and put it on its prototype canvas as image rows, one row per surface. Covers the company's own brand kit, the App Store, Google Play and Microsoft Store listings, verified social accounts, the newsroom and the marketing site; writing assets/brand/manifest.json with real pixel sizes, a source and a provenance on every file; wiring the folder's generator to read it; and verifying every file before it is listed. Use when asked to add b...
