/* Own visual identity. Deliberately NOT Exocharts' palette: they use blue=buy / red=sell on a
   near-black ground with their bundled condensed face. This is green/red on a cool dark ground.
   The LAYOUT follows theirs; the look does not.

   Two rules do most of the work in making this read as an application rather than a web page:

   1. Chrome is unselectable and takes a default cursor. Being able to drag-select the word "Tick"
      out of a toolbar is the single loudest tell that something is a document pretending to be a
      tool. Data stays selectable, because copying a number is a real thing to want.

   2. Labels are set in the UI face, numbers in tabular monospace. A trading screen is read by
      scanning columns of digits; when the digits are proportional the columns wobble and the eye
      has to re-find the decimal point on every row. Mono everywhere is the other failure mode -
      it reads as a terminal hobby project rather than a product.

   The type scale is three sizes and the radius is 2px everywhere. Restraint is the whole effect:
   more sizes and rounder corners is what "generated" looks like. */
