/* Omnes inner-page kit. Loaded after site.css on every inner page, never on the homepage.
   It adds the components inner pages share, in the homepage's language: open on the canvas,
   type, whitespace and hairlines. The only boxes are form fields, plus the page header's
   optional light-blue band. Every colour, font and measure comes from site.css tokens.
   Start each page from _template/index.html, which shows every component below.

   Index
   K01 Tokens          kit-only: --prose (long-form text), --danger (errors), --field-h, --measure
   K02 Shell           aria-current in the menu sheet; the first section after the page header
                       starts closer (.ph + .sec); .part (a second block inside a section)
   K03 Page header     header.ph (plain canvas) or header.ph.ph-tint (light-blue band), holding
                       .wrap.ph-grid (.ph-main: .ph-title the h1, .ph-lead, .ph-actions; optional
                       .ph-art: canvas data-field="mark"), an optional .ph-swell (canvas
                       data-field="swell", tinted band only) and an optional .wrap.ph-foot row
                       (breadcrumbs left, .ph-meta right)
   K04 Breadcrumbs     .crumbs: only in .ph-foot, never above the h1 (that reads as an eyebrow)
   K05 Section head    .sh: a serif .sh-title (h2) with an optional .sh-side (copy and a link);
                       .sh-inline puts a title and a link on one line; .sh-sub a smaller serif h3
   K05b Split          .split: a side column (.split-side, add .sticky to hold it) beside the
                       main one (.split-main), on the homepage FAQ's columns (1 to 4, 6 to 12)
   K06 Spec lists      .specs: term and definition rows between hairlines; .specs-grid: open
                       cells in three columns (.cols-2, .cols-4); .fig for a figure
   K07 Features        .features: open columns (three; .features-2 or .features-4), each .feature
                       a small light-blue tile (site.css .mt), a serif h3 and copy
   K08 Reading         .reading: an optional sticky .toc beside .prose (or .reading-solo);
                       .prose styles p, h2 (+ .n numbering), h3, h4, lists, a, strong,
                       .lede, blockquote, .table-wrap tables, .eq, figure, hr, sup refs, .footnotes
   K09 FAQ             site.css's open .faq accordion as the .split-main of a .split, the
                       group's .sh-sub in .split-side
   K10 Search          .filter row: .search field, .chips (.chip, aria-pressed), .search-count,
                       .empty
   K11 Forms           .form, .form-row, .form-field (label, .opt, .form-hint, .form-error), .select
                       (the chevron), .form .check (site.css) and fieldset.checks, .form-actions,
                       .form-status (.is-ok, .is-error, .is-busy)
   K12 Articles        .articles: an open list of .article rows (.article-meta, .article-t,
                       .article-d, .article-go)
   K13 Risk line       .risk: the short risk line that sits near economic content
   The closing panel is site.css .closing (18), used exactly as on the homepage.
