feat(website): website mise en place (#11552)

## Summary

Assorted website copy and content refinements — tidying up loose ends
across the site.

## Changes

- **What**: Remove placeholder doc links from custom nodes feature
description on pricing page

## Review Focus

Low-risk copy changes only; no logic or layout modifications.

> **Note:** The `PR: Vercel Website Preview` workflow is
`workflow_run`-triggered, so it always runs the **main branch version**
of the workflow file. Until this PR is merged, the preview workflow will
continue posting standalone comments using the old `<!--
VERCEL_WEBSITE_PREVIEW -->` marker instead of writing to the
consolidated `<!-- WEBSITE_CI_REPORT -->` comment. This is expected and
resolves itself on merge.
