lifesum.com is built on a pure-white canvas (rgb(255,255,255)).
The system uses rgb(33, 186, 58) as the high-saturation accent for primary actions.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside TTNormsPro as the primary typeface.
A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page.
Motion is a first-class concern — 27 keyframe animations plus transition-driven interactions.

17 enforceable rules pulled verbatim from the spec
Do
Use Near-Black (`#0e0e0e`) for text — not pure black, it's warmer and more readable
Use TTNormsPro as the primary typeface — it defines the brand personality
Use negative letter-spacing (-0.4px) at display sizes for compressed, editorial headlines
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use Success Green (`#21ba3a`) as the primary accent — it's the brand's signature interactive color
Use 8px border-radius on buttons — the standard corner rounding for interactive elements
Maintain nav height at 46.3438px — consistent vertical space for the navigation bar
Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
Each card includes a top image — imagery is part of the card identity, not optional
Don't
Don't use pure black (`#000000`) for text — the near-black adds warmth
Don't substitute with generic sans-serif or serif — the custom font carries the brand
Don't increase letter-spacing on headings — the type is designed to run tight at scale
Don't invent new shadow values — use only the extracted shadow levels
Don't introduce additional saturated accent colors — the palette is intentionally controlled
Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
Don't make the nav sticky — this design lets it scroll away to maximize content focus
