/* InsurEco artifact kit · document — the default.
 *
 * For reports, briefs, specs, plans and write-ups: a page someone reads top to
 * bottom. Layers on tokens.css (colour, type, brand) and iec-ui.css
 * (components); load all three, in that order:
 *
 *   <link rel="stylesheet" href="https://brand.insureco.io/tokens.css">
 *   <link rel="stylesheet" href="https://brand.insureco.io/iec-ui.css">
 *   <link rel="stylesheet" href="https://brand.insureco.io/kits/document.css">
 *
 * Every value resolves through tokens.css — there is no hex in this file, so
 * data-theme and data-brand restyle it with no extra work. Prose styles apply
 * inside .iec-doc only, so a chart library's DOM elsewhere is left alone.
