The client half of the host's new `os=` advert, shared once in pf-client-core:
`sanitize_os` (mDNS is unauthenticated input — lowercase `[a-z0-9._-]` tokens,
capped) and `os_icon_tokens`, the most-specific-first walk with the brand
aliases (`macos`→apple, `steamos`→steam) every platform resolves through.
`DiscoveredHost` carries the chain, `KnownHost` persists it (`serde(default)`,
elided when empty — older stores load unchanged and older clients read back
exactly what they wrote), `upsert` moves it only when carried, and `learn_os`
mirrors `learn_mac` — no-op, no disk write when unchanged — so the mark
survives the host going to sleep.
GTK shells: the card's status row leads with a recolorable symbolic glyph.
That needed real embedded assets — the shells had none — so `data/` gains the
ten `pf-os-*-symbolic` SVGs compiled into a gresource (new build.rs,
glib-build-tools) and registered on the icon theme at startup; the Adwaita
theme then tints them like every other status glyph.
WinUI shell: reactor renders raster-from-URI only, so the embedded mid-gray
PNGs (legible on both themes) materialize once into
%LOCALAPPDATA%\punktfunk\os-icons\ — the library's poster-art pattern — and
the tile's status row leads with a 16px image.
The couch UI plumbs `HostRow.os` (live advert preferred, else the store) for a
Skia glyph that is a declared follow-up; `--list-hosts` / `hosts --json` emit
the stored chain so the Decky plugin can read it. A host that advertises no
`os` renders everywhere exactly as it did before the field existed.

Break the 1212-line pf-console-ui/src/shell.rs into a facade + shell/ subdir
(shell.rs stays the parent; `mod render;` resolves to shell/render.rs):
- shell/render.rs : the per-frame screen compose/transition path (Shell::render
+ the LayerEnv paint helper)
- shell/overlays.rs : the modal overlays (Shell::draw_overlays + draw_takeover)
- shell/tests.rs : the inline #[cfg(test)] module, extracted verbatim
The Shell struct + its public API + draw_aurora() stay in shell.rs (both children
reach draw_aurora + the private fields as descendants — no bumps). Sole visibility
change: draw_overlays -> pub(in crate::shell) (its caller Shell::render is now a
sibling). Zero re-exports needed (Shell/ConsoleOptions never leave the root). Pure
move; no behavior change.
Verified both platforms: Linux (home-worker-5) clippy -p pf-console-ui
(--all-targets -D warnings) + test; Windows (winbox, ASCII CARGO_HOME) clippy.
