One identity: an annual report with a skyline concrete building on the cover — bought because nothing surprised anyone.

1. PALETTE (Fixed)

Surfaces: pure white #FFFFFF for the page, #F8FAFC for panels, #F1F5F9 for hover/inset.
Ink: #0F1722 (headings, primary), #3B4657 (body), #5B6777 (secondary/muted).
Borders: #E1E7EF (1px). Stronger: #C7D0DC.
Accent — exactly one: deep blue #1F4FE0. Used for: one primary button per viewport, links, active states, one emphasis mark. Nothing else.
Success/danger exist as status colors with fixed token semantics (success green #0E7F4B, danger #C0362C) — status only, never decoration.
NO gradients, NO hard shadows (soft 0 1px 2px rgba(15,23,34,0.06) max — usually not needed), NO dark hero sections on marketing pages.

Display: system sans (the platform's default) at 500–600 weight, clamp(1.8rem, 3.6vw, 2.8rem). Enterprise display is calm and specific — "integrations", not "transcend". NO display serifs, NO uppercase headers, NO oversized heroes (hard cap 2.8rem).
Body: system stack, 15–16px, 1.6. Secondary text for descriptions.
Labels/metadata: 12–13px, weight 500, #5B6777. Small caps optional, letterspacing ≤ 0.04em.
NEVER: italic body, text under 12px in marketing surfaces, more than 3 weights on a page.
