Builder clarity: a visible five-column grid, extra-wide type and two colours plus ink.
Why
Wide, extended numerals and strict two-colour systems mark the strongest builder pages this year. Cobalt goes stricter: two colours plus ink, with wide type used as architecture.
Hero
Five thin column rules stay visible. A huge uppercase headline spans the first four columns, and a square cobalt block holds the logo in the fifth.
3 palettes, one accent at a time.

Moment
Width Sweep
The project name starts narrow in the middle column and widens in 12 hard steps until it fills all five, while a cobalt fill sweeps in behind the letters.
- 01Movement happens in visible steps, like a mechanism clicking into place.
- 02Transitions take 0.5s and are never blurred.
- 03On hover, a button's accent edge slides to full width in six steps over 300ms.
- 04The name widens in 12 hard increments, in time with the grid.
- 05A build log under the hero cycles through the step titles.
