/* tools/generator.css — the public invoice and quote generators
   (/tools/invoice-generator and /tools/quote-generator).

   One stylesheet for both, as there is one template (templates/tools/
   generator_base.html) and one controller (static/js/controllers/esm/
   document_generator_controller.js). The `ig` prefix predates the quote page
   and is kept rather than churned through every selector.

   The document is the product, so it gets the room: a narrow fixed editor on
   the left, the paper floating on the canvas to the right at up to its true A4
   width. The editor is deliberately quiet - one white card, hairline group
   rules, small labels - and everything the ATO does not require is folded into
   a disclosure, so the tool sits inside roughly one screen.

   Every colour is a token from the public shell (--white, --border, --orange,
   --sandstone, --text-2, --black, --alert-danger-*). No hex literals: the
   design token ratchet allows this file zero. */
