DTTT · WEB DESIGN SYSTEM · v1.0

Web design system

The brand framework, applied to the web. A spec-grade catalogue of foundations, components, page templates, and content rules — built on the brand's tokens but with a web-native register: Inter for UI, IBM Plex Serif for editorial moments, flat radii, real elevation, a 12-column grid.

Radii4 / 8 / 12 / 16 / 24 / pillWeb-flat. Squircles dropped for the web register.
ElevationReal drop shadows + hairline ringWeb users expect lift on cards/menus. Hairline alone reads flat-print.
Grid12-col, 1280 max, 24 gutterIndustry standard, plays nicely with marketing + product surfaces.
Brand spineTeal scale + ink + grade scalesUnchanged from the brand framework — same DNA.
Sister file. The Apple-HIG brand register lives in ../figma-handoff/. This web system reuses the same colour and grade tokens but applies them in a web-native register. Use the brand register for proposals, presentations, and comms; use this web system for product, marketing pages, dashboards, and assessment tooling.
