Add keyboard-shortcut (Ctrl+C / Ctrl+X / Ctrl+V) text clipboard transfer
between the browser and the remote desktop, reusing the clipboard protocol
that already exists in the native viewer (COMMAND_SCREEN_GET_CLIPBOARD=24,
COMMAND_SCREEN_SET_CLIPBOARD=25, TOKEN_CLIPBOARD_TEXT=118) so the client
needs no change.
Local -> remote: pressing Ctrl+V reads the browser clipboard, pushes it to
the remote clipboard (UTF-8 -> GBK, matching the client's CF_TEXT/ANSI
handling) and then synthesizes a remote Ctrl+V so the pasted text is the
newly delivered one.
Remote -> local: Ctrl+C or Ctrl+X is forwarded to the remote as usual and,
after a short delay, the remote clipboard is pulled back and written to the
browser clipboard for a later local Ctrl+V.
Both the MFC and Go servers get the same three clipboard signaling paths
(clipboard_set, clipboard_get, clipboard_text) so the shared single-page
frontend behaves identically on either backend.

SOCKET_DLLLOADER (210) is the shellcode / memory-DLL loader asking the
server for the full DLL payload before it can load the client. The MFC
master console serves it via SendServerDll; the Go web device port has no
payload to hand out, so every memory-DLL client startup/reconnect fell
into the default dispatch branch and logged "Unhandled command 210",
flooding the log. Add a protocol constant and drop the command silently.
While auditing the device-port logging surface:
- Downgrade wrapTLS's per-connection hex-dump lines and the screen-spy
"[timing]" cold-start line from Info to Debug (they fire once per TCP
connection / screen view and are diagnostics, not operational events).
- Distinguish a sub-connection hijack attempt from a plain orphan: when a
screen/terminal sub-conn claims a MasterID from a source IP other than
the device's login conn, log a dedicated Warn instead of mislabeling it
as "orphan ... unknown device".

When the web remote desktop is mounted under another domain's subpath
(YAMA_WEB_BASE_PATH non-empty), read the product title from
YAMA_WEB_BRAND_NAME, substitute it for the SimpleRemoter titles and
PWA manifest name, and strip the security notice and website links.
The brand name is JSON- and HTML-escaped so operator input can't
produce malformed output. Served from the domain root, the official
SimpleRemoter branding is left unchanged.

The TCP device port is exposed directly to the public internet, so a single
host must not be able to exhaust the global connection budget, flood new
connection attempts, or brute-force the device authorization passcode.
- server: cap concurrent connections and the accept rate per source IP
(defaults 256 concurrent / 120 per minute, overridable via
YAMA_PERIP_MAX_CONNS and YAMA_PERIP_CONN_RATE). Rejections happen at
accept time, before any buffer or goroutine is allocated, and a rejected
device simply retries on its reconnect loop.
- cmd: throttle TOKEN_AUTH per source IP (120/min) and answer over-limit
attempts with a normal failed response so clients get a definitive reply.
- web: periodically sweep the login rate-limit maps so the username-keyed
one (which is attacker-controlled) cannot grow without bound.
Per-IP defaults are generous enough that a NAT office whose devices share
one source IP is unaffected.

Bridge an already-authenticated portal session into a YAMA web session via
a new /sso endpoint, so portal administrators can enter the remote-desktop
UI without a second login. Only the "admin" portal role is bridged; any
other role (viewer, unknown) still falls back to the built-in login form,
so a low-privileged portal account cannot bypass authentication.
- wsauth: extract IssueToken from VerifyLogin so an out-of-band-authenticated
identity (SSO) can mint a session token without the challenge/response.
- web: add the SSODetector interface, a fail-closed JWT detector (HMAC-only),
and the /sso handler gated to the admin role.
- cmd: enable the JWT detector via YAMA_SSO_JWT_SECRET, the shared HS256
secret matching the parent portal.
- web UI: attempt SSO before showing the login form, falling back to login
when the server returns 401.
- docs: document SSO (admin-only) and license trial-vs-paid troubleshooting
in README and the env example.

iOS WebKit lacks Media Source Extensions with WebM/Opus, so remote audio
was silent on iPhone Safari/Chrome even though audio frames kept flowing.
Add a Web Audio API fallback path that decodes Opus packets with the
`opus-decoder` WASM library and schedules them onto an AudioContext.
The decoder bundle is now self-hosted — served at /static/opus-decoder.min.js
by both the Go and C++ servers — instead of pulled from a CDN, which was
unreachable from some networks.
Gotcha fixed during bring-up: the unscoped `opus-decoder` build's
`OpusDecoder.decodeFrame` is synchronous and returns {channelData,
samplesDecoded, sampleRate, errors} directly, not a Promise, so it must be
called in try/catch rather than via .then().
Also remove the on-screen diagnostic overlay (audio toast + frame counter)
used while debugging the phone without a console; diagnostics now go to
console.* only.

Add optional YAMA_WEB_BASE_PATH to mount the whole web UI (index, manifest,
static assets, /health, /api/devices, /ws) under a URL prefix such as
/remoter behind a reverse proxy. index.html now uses a __BASE_PATH__
placeholder substituted at serve time, the PWA manifest start_url is rooted
at the base path, and a mount wrapper redirects the bare prefix to prefix/
and strips it before routing. Include nginx, systemd, and env-file deployment
examples for the subpath setup.
The shared placeholder is also handled by the MFC server, which serves from
the domain root and strips __BASE_PATH__ (to "") so its web remote desktop
URLs stay rooted.
