Replace the free-text target-version field with a select populated from versions
known across the fleet (each host's running + targeted version, newest first),
plus a 'custom...' escape to a text input for a version not yet seen. Avoids
typos on the pin. (Authoritative serving-side source is a follow-up.)
- Contrast: lighten the muted/faint text tokens (AA on the hull panels) and make
Monitor host-card data values bright ink against dim faint labels, so version/
tmpfs/seen details read clearly on the blue-grey panels (was grey-on-grey).
- Lifecycle: reboot selector now offers none | now | at... — 'now' sets
reboot_at to the current time (agent reboots on reconcile); still confirm-gated
as a high-consequence action.
The themed single-page admin UI (serving/fleet-manager/ui/), embedded into the
binary and served same-origin over the admin plane.
- Svelte 5 + Tailwind 4 + Vite; a sibling of serving/kiosk-app. Theme = LYSANDRA
'restricted-violet' (high-security evolution of the kiosk's flight-deck DNA):
amber deck, VIOLET reserved for privileged/destructive + auth surfaces, teal
telemetry, red alert, clearance chrome (corner-reticle panels, scanlines, mono
clearance labels, secure-link status bar).
- Passkey gate: Login (usernameless discoverable WebAuthn) + Enrol (from the
register-admin one-time link) via navigator.credentials, with base64url<->buffer
helpers and the go-webauthn response shapes.
- Three pillars over the JSON API: Monitor (fleet roster + version-drift + health
+ per-host detail with bespoke SVG telemetry charts), Authorise (pending queue:
fingerprint cross-check, approve+bind in violet, deny), Lifecycle (desired-state
form; drain/reboot confirm-gated). Session-aware fetch client (cookie + CSRF).
- go:embed behind the build tag (spa_embed.go / spa_stub.go) so the
default go build/test need no dist/; mounted at / (api/auth/healthz win).
Verified: npm build clean (71KB JS / 33KB CSS + self-hosted fonts); default +
-tags embedspa go builds; smoke test serves index + assets + API through the SPA
origin. Against an insecure+seeded backend the deck renders passkey-free for
theme work. dist/ + node_modules gitignored.
