Rebuild the page actions row: Copy as markdown and Open in Claude

[enf0rc3]

Implements two designs from Documentation vision: Open in LLM and Copy to clipboard.

What changed

The "Use Octopus docs with AI" pill at the foot of the article is gone. Under the page header, next to Edit on GitHub, there are now two actions:

Copy as markdown — fetches this page's .md companion and puts it on the clipboard. Swaps to a check icon and "Copied" for two seconds, then reverts.

Open in Claude with a caret — the primary half opens Claude with a prompt pointing at the page's .md URL. The caret opens a 256px menu of Open in Claude, Open in ChatGPT, Open in Gemini, as link-styled rows with a provider logo and an external-link icon.

Both are the Button component, so borders, radius, hover, pressed and focus states come from the design-system tokens. Button gains an as prop so the caret can be a <summary>; the split button's two halves collapse into one divider via a negative margin, which keeps each half's focus ring unclipped. Menu chrome uses --colorMenuListBackground* and --shadowMedium, so both themes work with no extra rules.

Four icons added under src/assets/icons/, exported from the Figma file and applied as CSS masks so they take --colorIconPrimary in a button and --colorTextLinkDefault in the menu.

Reusing the shared copy module

copy-button.js (from #3317) grows two things rather than the copy action reimplementing them:

• showResult writes to .btn__label when there is one, and falls back to the tooltip otherwise. The design wants the result in the label; the two existing icon-only consumers are unchanged.
• copyFetchedOnClick covers text that has to be fetched. It hands ClipboardItem a pending promise so the click's user activation survives the request — awaiting the fetch first and then writing loses it in Safari, which is the trap the module's own comment warns about.

The button also locks its measured width before the label shortens, so "Open in Claude" beside it doesn't shuffle. Measured rather than hardcoded, so it holds for any translation.

The eligibility check both actions need moved to pageMarkdownUrl(), so neither component re-derives the slug.

Fixes a markdown emitter bug on Windows

globSync returns backslash-separated paths on Windows and llm-md-emitter.ts fed them into forward-slash logic in two places. Two lines of posix: true:

• pathToSlug strips a trailing /index, so argo-cd\index kept its suffix and the page was written to dist/docs/argo-cd/index.md. Every request for /docs/argo-cd.md 404d, taking the page actions and llms.txt parity with it.
• The shared content lookup keys off path.posix.join, which leaves a backslash mid-key and never matches the include paths in the source files. A page whose include failed to resolve was judged ineligible, so 1252 rather than 846 pages now get a .md companion on a Windows build.

Linux was unaffected, which is why this survived. It is in this PR because it is what the two new actions point at.

One thing to call out

Gemini points at AI Studio. gemini.google.com/app has no native prompt parameter — the ?prompt= trick needs a browser extension. The label stays "Open in Gemini" per the design while the href is aistudio.google.com/prompts/new_chat?prompt=…, which does prefill. Happy to change the label if that reads wrong.

Testing

astro build from a clean dist: exit 0, 2673 pages, 1252 .md emitted.

tests/llm-endpoints.spec.ts: 13 passed, 0 failed. The two CopyMarkdown tests are rewritten and two added for the copy action, including one that clicks it and reads the clipboard back to confirm the page markdown actually arrives. Before the emitter fix, five of these failed.

Verified in a real browser in both themes: menu open and closed, and the copy button through rest, copied and reverted.
