   POPOUT — app.css

   Two jobs, in this order:
     1. THE DESIGN TOKENS. One :root block, kebab-case custom properties,
        grouped by comment banner (house style §7). dash.css and every future
        stylesheet consume these and define no raw hex of their own.
     2. The reset + the marketing / sign-in page at the APP_HOST root.

   No @import: an @import is a second serial round trip before first paint, and
   the shell can simply <link> both files. No web fonts either — the type stack
   is the system stack, which is already on the device, renders at 0 ms and
   costs no layout shift. §9.5's dashboard CSP is `default-src 'none'` with
   `font-src 'self'`, so a CDN font would be blocked anyway; not asking for one
   is better than being refused one.

/* ── THERE IS NOT ONE `style=` ATTRIBUTE IN ANY POPOUT HTML FILE ──────────
   §9.5's policy for this origin is `style-src 'self'` with no 'unsafe-inline',
   and that directive governs the STYLE ATTRIBUTE: a `style="display:none"` in
   markup — or an `el.setAttribute('style', …)` from script — is DISCARDED by
   the browser, silently, with the element simply ignoring every declaration.
   (Measured against this exact policy: setAttribute gave computed
   `display:block`; the same declarations via the CSSOM gave `display:none`.)

   So: state that HTML needs at load time is a class, like the two below;
   anything genuinely dynamic is written through the CSSOM from script, which
   `script-src 'self'` already governs and CSP does not treat as inline style.
   See the `style` branch of el() in js/dash-core.js. */
