Comparison target

Source visual truth: C:\Users\david\.codex\generated_images\019f92c1-c086-7b62-9e3e-8942418c08bb\exec-92a2158c-b865-4c30-a1af-bd75a8410bd2.png (the selected final design, option 1).
Supporting product references: docs/screen/login.png, docs/screen/workspace.png, docs/screen/export.png, docs/screen/p3.png, and docs/screen/p4.png.
Intended implementation: apps/site/index.html at a desktop viewport matching the selected long-form landing page.
Implementation screenshot: unavailable.

Source assets were opened and inspected before implementation.
The page uses the supplied official logo and product screenshots rather than recreated logo or product-preview artwork.
Primary interactions in code: “下载” scrolls to the download section; “WEB 登录” links to https://agent.senlin.ai.
Static resource validation passed: all six referenced assets exist and the WEB login URL is present.
Backend tests and the existing web_v1 production build passed.

Fonts and typography: implemented with the existing Chinese system-font stack, a high-contrast display hierarchy, and compact utility text aligned with the source system.
Spacing and layout rhythm: implemented as an 1440px-centered desktop grid with a left text / right product-preview hero and responsive single-column fallback.
Colors and visual tokens: uses the source product’s cobalt #165DFF, pale gray workspace surfaces, thin blue-gray separators, and navy footer/status treatment.
Image quality and asset fidelity: uses supplied SVG logo and supplied product captures for workbench, exploration, documents, and AI conversation.
Copy and content: includes project context, exploration data, project documents, expert AI conversations, private deployment, and human confirmation.

[P1] Browser-rendered visual comparison is unavailable.
- Evidence: the in-app browser could not initialize in this environment because of a system path error, so no implementation screenshot or same-viewport composite comparison could be captured.
- Impact: typography, crop, spacing and responsive behavior have not been verified against the selected visual target in a browser.
- Fix: restore in-app browser access, capture the homepage at the selected desktop viewport, compare it side-by-side with the source visual, and resolve any P0/P1/P2 differences.

Initial pass: blocked before browser capture; no visual comparison iteration is available.

final result: blocked
