/* mm24 dealing desk.
 *
 * Dark and dense on purpose: this is a screen someone watches, not a page
 * they read. The rules that matter:
 *
 *   - NUMBERS ARE TABULAR AND MONOSPACED. A price column that shifts as
 *     digits change is a column you cannot scan, and comparing two figures
 *     by eye is most of what this screen is for.
 *   - SIGN IS COLOUR, and only sign. Green and red are never used for
 *     anything else, so a red cell always means "this is costing money".
 *   - NOTHING IS ROUNDED HERE. Every figure is the string the server sent
 *     (public/format.js only trims trailing zeros). The columns are sized
 *     for 38-digit NUMERICs rather than clipping them.
