What changed — and which rule did it
Pure #000 headings
Darkest text is #2A2A2A — 5-level grayscale hierarchy
Blue, green, purple, orange all fighting
One accent. Everything else grayscale — restraint is elegance
1px gray borders on every box
Borderless cards — tone + ≤8% shadow do the separation
Number and unit the same size
Numbers 2:1 with units — 48px value, 24px unit
Four identical KPI boxes in a row
Varied sections — hero, mixed KPIs, list. Rhythm, not repetition
Content sits on bare background
Everything lives in cards on a toned page
No motion, or a random fade
Named seed entrance — intentional, consistent, replayable
These 7 are the visible ones. The full design language has 69 rules — color discipline, spatial rhythm, hierarchy, elevation, component variance, motion.
