/* One-screen splash layout for tools: the interactive visual on the right fills the
   viewport under the site nav, a compact intro and controls sit on the left, and
   everything else follows below the fold. --sp-top is set by /tools/splash.js.
   Desktop areas: intro and ctrl stack in the left column, stage spans both rows.
   Phones: intro, stage, ctrl, so the visual is on the first screen. */
