/* Syn Bank Coverage Desk
 *
 * Design direction: an institutional coverage terminal, not a data-science
 * notebook. The one idea the visual language carries is the thing this whole
 * project is about — that the five pillars are not the same kind of claim.
 *
 *   The range mark      every figure that is a range is drawn as one: a band
 *                       from low to high with a dot at the base. Cash, which is
 *                       identity-anchored, gets a dot with no band. The reader
 *                       learns the difference without reading a word.
 *   The pillar grammar  CORE pillars carry a solid accent rule, SUPPORTING a
 *                       two-tone half rule, SIGNAL_ONLY a dotted one. Repeated
 *                       at every scale so "this is a different kind of number"
 *                       is structural rather than a footnote.
 *
 * Colour is indigo: one accent, a sequential indigo ramp for magnitude, and the
 * reserved status four. NO GRADIENTS ANYWHERE — every fill in this file is a
 * flat colour or a border. The half rule is two solid blocks; the dotted rule is
 * a real dotted border. A gradient would make magnitude ambiguous in exactly the
 * places this dashboard is asking to be trusted on magnitude.
 *
 * Two type voices, both from the system stack because the dashboard must run
 * with no network:
 *   the sans   headings and figures. Tight tracking, tabular numerals.
 *   the mono   every label that names rather than states — eyebrows, table
 *              heads, chips, ticks, ranks. Instrumentation, not prose.
 *
 * Hairline discipline: cards are borders, not shadows. Shadow is reserved for
 * things that genuinely float — the tooltip, the copilot, a hovered heat cell.
 *
 * Light only, with an explicit colour-scheme, so it renders identically on a
 * judge's dark-mode laptop.
