Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change adds Markdown page outputs, an llms.txt index, and footer links, but the current link generation may produce incorrect or non-resolving Markdown URLs under site-path or output-format configuration. That concrete feature risk should be fixed or explicitly accepted before merging; missing titles and metadata differences are lower-impact follow-ups. Sequence Diagram(s)sequenceDiagram

Preserve document-level title structure in both Markdown templates.
Both templates emit the page title as plain text. Render the title as # {{ .Title }} in layouts/_default/list.md and layouts/_default/single.md.

Hugo Page OutputFormats.Get markdown Permalink RelPermalink documentation
💡 Result:
In Hugo, the.OutputFormats.Get method is used to retrieve a specific OutputFormat object by its identifier (e.g., "html", "rss", "json") from a page's collection of enabled output formats [1][2]. Once you have successfully retrieved an OutputFormat object using.Get, you can access its associated properties and methods, including.Permalink and.RelPermalink [1][3]. Usage Pattern To use these methods, you must chain them after selecting the specific format [4][5]. For example, to create a link to an RSS feed for the current page: {{ with.OutputFormats.Get "rss" }} RSS Feed {{ end }} Key Methods and Properties.Get "identifier": Returns the OutputFormat object associated with the provided name (case-insensitive) [1][6]..Permalink: Returns the absolute URL of the page for that specific output format [1][3]..RelPermalink: Returns the relative URL (path) of the page for that specific output format [1][4]. Important Context By default, the standard.Permalink and.RelPermalink methods on a Page object return the URL of the primary output format (typically HTML), regardless of the template in which they are called [7][8]. If you want these global methods to return the URL of the current template's output format instead, you must set the permalinkable configuration parameter to true for that specific output format in your project configuration [7][8].

hugo.toml sets .Site.Params.description to Product Documentation, so the output ignores content/en/_index.md's description.

Align the new footer block with the surrounding markup.
The view-markdown span is indented more deeply than adjacent spans, and its Go template block uses a different indentation level. Align these lines with the surrounding footer structure.
As per coding guidelines: layouts/**/*.html: follow Go template syntax, use partials for reusable components, maintain consistent indentation, and prefer Hugo built-in functions when possible.

Closes #1205
What this does
Every content page now publishes a clean Markdown sibling (/index.md) containing only the substantive content — no navbar, sidebar, or footer — plus a site-wide /llms.txt index and a visible "View as Markdown" link in the page footer.
Upstream investigation (per the issue's sourcing requirement)
Hugo core already provides a built-in markdown output format (text/markdown, isPlainText) in its default formats, so no custom Go code or media type is strictly required — the capability is native.
Docsy added first-class "agent support" (Markdown page output + a "View Markdown" page-meta link + llms.txt) in v0.15.0 (May 2026), via PRs #2597, #2599 ("Drop Markdown output fmt since Hugo defines it"), #2601, #2605, #2606.
This repo pins Docsy v0.14.3 (go.mod), which predates that release, so the upstream feature isn't available to us yet.
Approach
Since upstreaming isn't an option at 0.14.3, this backports the capability locally using Hugo's native output-format mechanism:
hugo.toml: declare markdown + llms output formats and add them to the page/section/home outputs.
layouts/_default/single.md and list.md: emit .RawContent for clean page/section Markdown.
layouts/index.llms.txt: generate a spec-compliant /llms.txt (H1, summary blockquote, ## Docs link list).
layouts/partials/footer.html: add the visible "View as Markdown" link beside "Edit This Page."
Recommendation: when Docsy is upgraded to ≥0.15.0, this local backport can be removed in favor of the built-in agent-support feature.
Testing
Built and served locally with Hugo Extended v0.164.0 (deploy target is v0.140.2 per CONTRIBUTING; the features used exist in both). Verified: doc pages render normally, /index.md returns clean Markdown, /llms.txt lists all pages, and the footer link resolves correctly.
