/* ============================================================================
   The Financial Sciences Company — assets/tfsc-article.css
   Article shell v1 (2026-09-03).

   The RMC article shell (left TOC | article | right rail, Short Answer box,
   tip callouts, Keep Reading grid, monthly note) ported to the TFSC brand kit
   per Theo's direction 2026-09-03. Layout structure is RMC's — it tested well
   and he wants it as the firm's standard. Every token is TFSC's own:
   Ink / Brass / Bone / Paper / Steel, Playfair Display / Manrope / JetBrains
   Mono. Brass stays on the argument only (Short Answer rule, active TOC item,
   arrow glyphs) and well under the 8% ceiling.

   Wired on article pages AFTER the site's existing stylesheets:
     <link rel="stylesheet" href="/assets/tfsc-article.css" />
     <script src="/assets/tfsc-article.js" defer></script>

   EVERY class is namespaced `tfsca-` so nothing collides with, or has to
   out-specify, the Astra/Elementor CSS already on the page. Where Astra styles
   a bare element inside .entry-content (h2, table, ul) the override is scoped
   under .tfsca-body, which wins on specificity without !important.
