/* Dartabase: the register.
 *
 * Derived from the Claude Design "Dartabase" canvas. Two deliberate departures
 * from that file, both recorded in docs/interface-spec.md terms:
 *
 *  1. The wordmark carries the Nepal roundel and the flag crimson, at the
 *     owner's direction. The independence line is therefore given more weight
 *     than the canvas gave it: it sits in the masthead, not only the footer -
 *     so the page still states plainly that this is not a government register.
 *  2. Gregorian dates are primary everywhere, Bikram Sambat secondary, including
 *     at month precision, where the canvas had it the other way round.
 *
 * The accent (--steel) is reserved for provenance. It appears on rails, marks,
 * citations and nowhere else. Not on buttons, not on links, not on headings.
 * If you are reaching for it for anything else, reach for --ink instead.
