Small page for display latency between client and server.
The time displayed is the duration between a client emits event and receives event back.

Use the exact Calcit version in deps.cirru (currently 0.30.1-alpha.4), Node 24 and
Yarn 4.12.0. Calcit CLI and @calcit/procs must match; this is a published
prerelease pair, not stable Calcit 0.30.1. Module dependencies use exact release tags.
本轮实际配对到 0.30.1-alpha.4，并同步 Cumulo Reel、Recollect、WS-EDN、
Respo/UI/Message 及 Util 的正式模块版本；稳定 0.30.0 消费者不能混用新旧图。
清理 8 个 namespace 的旧 imports [] 标记，并将 8 处同实现的旧 defatom
声明改为 defref，保留初始化表达式、Ref schema 和重载状态行为。两处初始 diff 输入从
Option<ClientStore>.unwrap-or nil 改为显式 Some/None 分支：已有值原样使用，
缺失仍用 nil 生成/恢复初始快照，不增加强转、重复解码或业务默认值。
calcit.cirru is the canonical source and deps.cirru is the module manifest.
The retired compact.cirru and package.cirru files are no longer used or tracked.

yarn release-pageyarn watch-page uses calcit calcit.cirru js -w: JavaScript generation and
watch mode are both explicit. In this CLI, -w belongs after the js
subcommand; calcit -w calcit.cirru js emits once and exits. The configured
default entry is already JS, so calcit -w calcit.cirru also selects JS watch,
but the explicit form avoids relying on that entry setting.
After saving structured CLI edits, publish the changed definitions through
calcit edit inc --changed <namespace/definition> to notify the running
watcher. Its ignored .compact-inc.cirru is a transient change notification,
not the retired compact.cirru source format; do not commit either generated JS
or the notification file.
The native server also needs calcit.std and calcit-wss built on its target
machine. Run cargo build --release --locked inside each installed module,
then copy its libcalcit_std / libcalcit_wss shared library into that module's
dylibs/ directory (.so on Linux, .dylib on macOS).

Back up existing data and validate a copy before upgrading a running server;
the service host must install the matching compiler and native dependencies
before consuming this source. Keep the server deployment at
/servers/display-latency/.

Frontend builds accept VITE_BASE_URL, defaulting to ./ for local use. CI
uses https://cos-sh.tiye.me/Cumulo/display-latency/ for production and the
separate pr/<number>/ prefix for each PR's assets. Only frontend dist/ is uploaded to COS;
the upload action performs its own public-file verification. Neither
js-out/, dist/ nor dist-server/ belongs in Git.
