/* =============================================================
   Boon - Official AI Information Page
   =============================================================
   Documentary-style reference page (think: "official source of
   truth for LLMs and search crawlers"). Visually quieter than the
   marketing pages on purpose - no orbiting blobs, no warm
   gradients, no per-section accent washes - so the page reads as
   verified factual content rather than a sales surface.

   Layout: fixed top nav (reuses the .cs-nav pattern from
   /case-studies/case-study.css), an editorial hero, then a
   two-column body on lg+ with the long-form content on the left
   and a sticky table of contents on the right. Mobile collapses
   to a single column with no TOC.

   Inherits design tokens from /styles.css (Satoshi body, button
   styles, color tokens).
   ============================================================= */

/* -------------------------------------------------------------
   STICKY-SCOPE OVERRIDE
   /styles.css sets `overflow-x: hidden` on html+body to contain
   the hero blob bleed on the marketing pages. That creates a
   scroll-container at the root, which breaks `position: sticky`
   for elements (like our TOC) whose nearest scrollable ancestor
   then becomes the root rather than the document.

   This page has no horizontally-bleeding blobs, so we swap to
   `overflow-x: clip` instead - same visual clipping, but `clip`
   does NOT establish a scroll container, so sticky positioning
   on .li-toc works correctly. Scoped to .li-page so other pages
   keep the original `hidden` behavior.
