/* ============================================================
   VARIANT LAYER (type-level variance, June 2026)
   One system, distinct reading rhythms. Set data-variant on the
   <body>: "ledger" | "plate" | "editorial". Unset = base monograph.
   Selectors are structure-agnostic (never nth-of-type on section
   order) so a variant never depends on a page's section sequence.
   Composition and layout only: the single navy accent, the panel
   rules, type and color are untouched. Plus shared opt-in
   components any page may use: pull-quote, hero-spec, index-strip,
   and the block--alt full-bleed band.
