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.

2. TYPOGRAPHY (Fixed)

• 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.

3. COMPOSITION (Fixed)

• Conventional layouts are correct: left-aligned hero, 12-col grid, features in 3-col or alternating 2-col rows, a comparison table, a data table, clear footers with legal links. The page should feel like the safe choice — because for this audience, it is.
• Hero: eyebrow (13px, accent or muted) → H1 (2.2–2.8rem) → one-line sub → one primary + one secondary button → a bordered product/metric panel. No hero theatrics, no claims without evidence nearby.
• Evidence is the ornament: logos (grayscale), metric callouts with source lines ("Based on 2,400 customers, 2025"), compliance chips (SOC 2, ISO 27001, GDPR — as text chips, not illustrations), customer quotes with title + company.
• Tables are the signature component: 1px #E1E7EF rules, 12px header caps left-aligned, 14px rows, zebra optional, hover row = #F8FAFC. Pricing as a bordered table beats pricing cards.
• Cards: 1px border, 8px radius, header + body + optional footer; hover = border darkens, no lift. Radius 6–8px everywhere; pills only for status tags.
• Footers are complete: product/company/resources/legal columns, address, copyright, compliance badges.

4. CONTENT TREATMENT

• Every claim gets a qualifier or source. "Best" becomes "Highest adoption in our category (G2, 2025)".
• Emoji banned. Icons: 1.5px stroke set (same family throughout), 20–24px, #5B6777 at rest, accent at hover.
• Button language is concrete: "Start a trial", "Talk to sales", "Request a demo".
• Numbers: tabular figures, precise ("99.9% uptime SLA", "$29/month billed annually").

5. MOTION (Practically None)

• Hover states: background/border change only, 120–150ms, no movement.
• One entrance allowed: page-sequential section reveals (200ms, 6px, no stagger drama) — or nothing at all, which is also fine.
• No scroll animations beyond the above, no parallax, no autoplay carousels.

6. CHECKLIST (Fail the Page If…)

• Any decorative element that isn't earning trust (illustrations of people, gradient blobs).
• Any claim without a qualifier or source.
• Any text under 12px.
• More than one accent per viewport or any color carrying no meaning.
• Headline above ~2.8rem or any serif/uppercase display.
• Missing footer legal links or missing compliance signals on a regulated-audience page.
• Any table without proper alignment (numbers right, text left).
• A layout a procurement committee would squint at.
