01 / WHAT WORKS

What makes it work

Materials and color create recognition

Blue, black and white objects overlap against a dark scene, contrasting with the pale surrounding canvas.

Navigation stays calm around complexity

Simple brand text, positioning and pill controls keep the scene as the focus.

02 / NEXT STEPS

Where to go next

  1. 01

    Keep contact visible on mobile

    Desktop exposes LET’S TALK, while the mobile header mainly offers an ellipsis menu.

    Add a contact entry below the mobile scene or retain a short header label, reserving the menu for secondary navigation.

Parameters are element samples. Empty values are unknown, and individual samples are not site-wide rules.

04 / EVIDENCE

The detail behind the report

Values come from one capture. Fonts, radii and spacing are element samples, not a universal site-wide specification. Empty values are unknown. HTML bytes are source size, not compressed transfer size; script counts are DOM tags, not network requests.

No Content-Security-Policy

A CSP is the standard way to limit script sources. Vibe-coded pages often load anything, including injected scripts.

Start with a report-only CSP, then default-src 'self' and an explicit script-src.

Design baseline
Brand, positioning and contact/menu actions share the header. A large rounded 3D scene anchors the hero; crosshair details and a scroll cue lead into approach, featured projects and contact. Mobile places positioning above a vertical crop. This records the static scene only; interaction and animation timing require separate implementation and verification.

Acceptance
- Check text, layout and the main action “LET'S TALK” at 1440×900 and 390×844.
- Preserve branding, authentication and business behavior. A screenshot does not prove broken interaction.
- Change only evidence-backed issues. Validate security headers against existing resources and authentication in report-only mode where supported.
- Compare before/after screenshots and run relevant functional tests. Do not claim untested behavior passed.
