feat(vdisplay/gamescope): honor in-stream 'Switch to Desktop' under the managed DM takeover
First on-glass test of the DM-flavor takeover confirmed the black-screen
fix, but exposed that the managed model could not switch back: Steam's
in-stream session-select is a silent no-op while the display manager is
stopped (every config-write branch in os-session-select requires the DM
to be running), so the capture loss it causes just relaunched game mode.

The user pass of the switch script does leave one durable trace — the
~/.config/steamos-session-select sentinel, written before any DM check.
The managed launch now baselines its mtime; a capture loss with the
sentinel advanced reads as the switch request and is honored by
replaying the switch with the DM up: restore the display manager, run
the distro's own os-session-select (its internal pkexec is authorized
allow_any by the distro policy, so it works from the host's sessionless
context), then stop the autologin game-mode unit so Relogin lands in
the newly selected desktop. The capture-loss re-detection then follows
KWin as it comes up; a 120 s post-honor grace stops the rebuild loop
from racing the booting desktop back into game mode (superseded early
if the box's own game-mode unit reappears — the desktop→game leg stays
fast). The baseline is re-recorded on crash-restore so a pre-existing
sentinel never reads as a fresh request. Every verb in the sequence was
live-validated on the Nobara repro VM.

punktfunk-docs

The punktfunk documentation site: Fumadocs on TanStack Start (Vite + Nitro/bun preset).

Content lives in content/docs/ as .md/.mdx. This site is the source of truth for the user-facing guides; design rationale lives in the internal punktfunk-planning repo.

API reference

/api renders the host's management REST API as an interactive Scalar reference (linked from the top nav, the docs sidebar, and the landing page). It reads public/openapi.json — a snapshot of the repo's generated spec. Refresh it after a management-API change:

# from the repo root — regenerate the spec, then copy the snapshot in:
cargo run -p punktfunk-host -- openapi > api/openapi.json
cp api/openapi.json docs-site/public/openapi.json

Develop

bun install
bun run dev        # http://localhost:3001  (docs at /docs)

Build & serve

bun run build
bun run start      # serves .output/ via Bun
