/* Full Set Accounting — the whole look, in one file.
 *
 * No framework and no build step. That is a deliberate trade: a Malaysian shop
 * runs this on a VPS behind a slow line, and every megabyte of framework is a
 * second the invoice screen does not open. What is here loads once and caches.
 *
 * The rules that matter in an ACCOUNTING interface specifically:
 *
 *   1. Money is right-aligned and uses tabular figures. Columns of numbers that
 *      do not line up cannot be scanned, and scanning is the whole job.
 *   2. A negative is red AND carries a minus sign. Colour alone fails for the
 *      ~8% of men with a red-green deficiency, and this is money.
 *   3. The company you are in is visible at all times. Posting to the wrong set
 *      of books is the classic disaster and it is silent.
 *   4. DRAFT and POSTED never look similar. One is a piece of paper, the other
 *      is permanent.

 * BACKGROUND tint and never the only thing carrying meaning: a note still has
 * its coloured left border, a danger button still has red text. The screen
