Design a light-mode web interface screen: clinical monochrome architectural photography punctured by pure cobalt blue geometric badges and warm salmon accents.
LAYOUT
The page unfolds in a disciplined single-column grid maxing out at 1200px. It opens with an asymmetric split hero (text left, grayscale image right), followed by a centered 3-card service row and a full-width horizontally sectioned metrics band. A secondary split-feature section leads into an enclosed contact panel, resolved by a dense, grounding 4-column midnight blue footer.
PALETTE (use these exact hex values)
- #FFFFFF — Canvas White: Primary surface for page canvas, hero section, and clean card interiors
- #F8FAFC — Soft Surface Tint: Subtle cool grey fill for stat panels and contact form backgrounds
- #0B1325 — Footer Slate: Deep navy slate used exclusively for the high-contrast footer container
- #2563EB — Electric Cobalt: Primary action buttons, active icons, signature floating geometry, and brand anchors
- #EFF6FF — Cobalt Light Tint: Background tint for service card circular icon badges
- #EF4444 — Salmon Coral: Secondary CTA submit buttons and pill badge typography highlights
- #0F172A — Deep Slate Text: Main display headers, section titles, and high-emphasis body copy
- #64748B — Muted Slate Text: Descriptive paragraphs, metric labels, form placeholders, and sub-navigation
- #E2E8F0 — Border Subtle: Hairline perimeter borders on service cards, stats band, and text inputs
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter,General Sans,Urbanist), weights 400/500/600/700/800. Sizes 11px caption, 13px body-sm, 14px body, 16px body-lg, 20px subheading, 28px heading, 36px heading-lg, 52px display. Tracking -0.03em display, 0.08em uppercase badges. Plus Jakarta Sans delivers an unapologetically modern, direct, and architectural voice. Its wide aperture, geometric proportions, and tall x-height allow tight tracking (-0.03em) on large bold display headers without sacrificing optical balance. Inter or General Sans serve as seamless replacements without altering line measure.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 10px, buttons 10px. Spacing on a 4px unit, 24px gaps, 96px between sections, 1200px container, comfortable density.
DEPTH
Depth is handled predominantly through crisp 1px borders (#E2E8F0) and sharp white-on-light-gray surface stacking rather than pronounced shadows. Where shadows exist, they are barely perceptible ambient diffusions (#0F172A at 4% opacity with 20px blur) giving cards a floating paper feel. This deliberately flat, photographic aesthetic evokes printed architectural magazines.
IMAGERY
Photographs are strictly monochromatic, featuring stark, brutalist, or coastal architectural structures (lifeguard towers, concrete stairs, industrial boardwalks) framed in clean daylight. Images feature large 24px border radii and serve as tranquil gray textures. Using vibrant lifestyle photography, saturated colors, or generic corporate handshakes would immediately dismantle the editorial identity.
SIGNATURE DETAIL — the thing that makes this design itself
The asymmetric cobalt badge overlap: a vivid, solid blue (#2563EB) rounded rectangle deliberately overlapping the lower edge of a serene, black-and-white architectural photograph. To use it correctly, float it as an unadorned solid color anchor bridging photo and canvas; misuse occurs when text or icons are crammed inside, degrading its role as a pure geometric signature.
MUST
- Keep photographic imagery exclusively grayscale and architecturally focused to balance the bright cobalt accents.
- Use pill badges (radius 9999px) with generous letter spacing for all category pre-headers.
- Maintain high typographic contrast with font weights jumping directly from 400 regular to 700 bold.
- Allow generous section padding (80px to 96px) to maintain the airy editorial gallery aesthetic.
AVOID
- Do not introduce multi-color photography; color is strictly reserved for UI tokens and interactive states.
- Avoid heavy dark drop shadows; surfaces must remain luminous, flat, or faintly elevated with soft ambient blur.
- Do not round card corners completely into pills; cards remain 20px rounded rectangles.
- Avoid crowded form inputs; maintain clean 12px padding and minimum 10px rounded corners.
