/* HUGIN Console — the independent visual system.
 *
 * This file is the enforcement point for parity-spec FR-UI-013 ("own palette, own
 * type scale, own icon set, own chart defaults, specified and enforced in code") and
 * FR-UI-014 ("distinct layout signature"). The choices below are deliberate and the
 * reasoning is recorded here so a design review can check it, per FR-UI-021.
 *
 * Palette: a cool slate ground with an OCHRE primary and a TEAL secondary. No magenta
 * or pink anywhere, as a primary or in the categorical chart sequence — that is an
 * explicit FR-UI-013 prohibition. Ochre was chosen because it reads as "instrument
 * panel" rather than "web app", and because warm-on-cool gives a single accent enough
 * contrast to carry both selection and focus without a second hue.
 *
 * Type: the platform UI stack and the platform mono stack. No web font, because a web
 * font means a network fetch and HUGIN makes no connection the operator did not
 * configure. The scale is a 1.2 ratio from 12px, truncated to six steps.
 *
 * Geometry: 3px radius, 1px borders, 8px spacing unit. Tight and square rather than
 * rounded and airy — a distinct layout signature is the point, and a dense grid is
 * also the right answer for an operator reading a thousand rows.
 *
 * Layout signature: a persistent LEFT RAIL plus a command palette as the primary
 * navigation device, with a 40px header that holds context and nothing else. Both
 * halves of FR-UI-014's specified default.
 *
 * Light and dark are both first class: dark is the default for a console people watch
 * at 03:00, light follows the system preference, and `data-theme` overrides either.
