Trust anchor pages that crawlers and AI agents check before recommending a site, each with substantive content in the existing site design (new shared ContentPage layout), linked from the footer. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Custom 404 page (real HTTP 404 status via the Vercel build output) with recovery links: docs, pricing, blog, llms.txt, sitemap, contact - llms.txt with an explicit 'When to use Shepherd' section, install and API guidance, and links to docs and trust pages Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

example to state that loading shepherd.mjs requires a module import of its
default export before constructing the tour, while retaining the stylesheet link
and existing tour setup instructions.

to honor Do Not Track and limit collection to match the privacy disclosure:
enable respect_dnt, disable autocapture and page-leave capture, and disable
session recording while preserving the existing API host.

Import the ESM default export before constructing the tour.
Loading shepherd.mjs as a module does not create a global Shepherd binding. The browser example must import the default export in the module that creates the tour.

Reachability: External
Exploitability: Trivial
CWE: CWE-693
Honor Do Not Track and limit PostHog’s default capture.
respect_dnt defaults to false, so the current initializer does not honor the Do Not Track promise. PostHog also enables autocapture by default, including clicks, input changes, and form submissions. Configure the integration to match the narrower disclosure, or expand the policy to describe these events and any session recording enabled in the PostHog project.
