/* ============================================================
   WEBSITE BUILDER — "the browser"

   The product is a website, so the hero is a website: a browser
   chrome panel that swaps between the two tiers you can buy.
   Static is shown as a clean wireframe; full design is shown with
   graphics and motion switched on. The difference between $300
   and $450 is a thing you look at rather than a bullet list.

   Electric blue over near-black, square-cornered and precise —
   the closest page to the parent brand, because this division is
   Kellstar building the thing Kellstar is made of.
