    .Finishing the CSS style for the comparison table seems necessary. The missing piece likely involves defining the border color, which is currently linked to a CSS variable. The next step is to examine the CSS file to find the definition of `--border`.


Inspecting the CSS reveals the definition of `--border`. Applying this to the table elements completes the styling. Now, moving to the HTML structure, the basic table structure needs population with content.


Now focusing on the overall page structure, identified thirteen distinct sections, including a FAQ accordion, guarantee badges, and a contact form. These must now be integrated. A footer and sticky call-to-action bar also need inclusion in the layout.
Local image paths are available for content population. It is critical to adhere to the restrictions. It seems useful to examine existing content to better understand these sections and any existing constraints.


The focus now shifts to crafting the CSS for the remaining components, including the testimonials grid, insights grid, FAQ accordion, guarantee bar, contact form, sticky CTA bar, footer, and responsive media queries.

The HTML structure for these components is the next task. Starting with the top bar, header and main sections including the hero section with its image, metrics section, architecture overview, and advantages section will need to be written.

The images paths available will be used to populate content restrictions.


Now examining the detailed section content to build out the HTML structure. Each section ID corresponds to the available components; these will be integrated into the page layout. The available image assets will be integrated into the respective sections. The security section will integrate the available features (Dark risk control engine & data pipeline).
