// ---------------------------------------------------------------------------
// Styles — one module-level stylesheet (the `wk-` prefix scopes it to this
// app's iframe) rendered once at the root as <style>{CSS}</style>. Every
// color/font is a CSS token painted by the Möbius shell, so the app inherits
// future themes for free. Render-time dynamic values (per-category accent
// colors, the measured chat-panel height, the bar-fill %) stay inline; every
// app-driven state that used to be an S.foo(active) helper is now a modifier
// class (.is-active / :disabled). Shared-chrome blocks are fenced with
// mobius-ui markers so a future extraction is mechanical.
