/* ==========================================================================
   desktopSubstrateStyles.css — the substrate window (desktopPanel family)

   Ported from the standalone project's sphereStyles.css: the white
   stage untouched, the dark instrument sidecar beside it, every
   control hard-edged (radius 0), each pool section inked by its own
   liquid color through --accent set inline from JS.

   Port deltas, all structural:
     - Everything is SCOPED under .desktop-substrate — the source's
       :root vars, `html, body`, and `*` rules would leak site-wide.
       Custom-property NAMES are kept for diffability; scoping makes
       them shadow, not collide. --accent is explicitly re-grounded
       below: the site's :root sets it to brand red, and without the
       re-ground every slider OUTSIDE a pool section would inherit it.
     - IBM Plex Mono → the site's Glitched family: "Glitched" for
       display (masthead, block titles, names, buttons), "Glitched
       Book" for labels and readouts. Plex's tabular-nums kept the
       readouts from jittering; Glitched has no tabular figures, so
       .val gets a fixed right-aligned slot instead.
     - The 760px viewport media query → a container query: the window
       resizes by drag, not with the viewport (container-type sizing
       per the desktopAudio precedent). The query restyles an inner
       .substrate-frame because a container cannot restyle itself.
     - The hint chip (CLICK TO RESUME) is new — pure CSS off
       :focus-within, desktopGame's hint adapted to focus-within
       liveness and to a white stage. The appear delay swallows the
       one-frame gap between window insertion and the deferred
       auto-focus landing.
