/* CHG-WEB-004 / PHASE-3 / STEP-06 — General How It Works (/how-it-works/).
   Page-specific composition glue only: marketing-section/section-split/
   mechanism-step-index/trajectory-sequence/trajectory-stage/
   trajectory-status/ai-comparison-grid are all reused, unedited, from
   ../styles.css.

   Hero grid geometry applies PRODUCT_PAGE_VISUAL_SYSTEM_v0.1 (same
   validated mechanism as every prior product/overview page): a
   page-scoped .ghiw-hero-grid class overrides align-items to stretch at
   1024px+ on THIS page's own .hero-grid element only (../styles.css's
   shared rule, used by the Homepage and every other page, is untouched).
   The visual panel is a flex column whose svg fills remaining height via
   flex:1 1 0%/min-height:0, scoped to the same 1024px+ query so
   mobile/tablet stacking never risks the flex-collapse failure mode
   documented in STEP-04B.3. The svg uses width:100% + explicit
   preserveAspectRatio="xMidYMid meet" (contain-like). No transform:
   scale() is used anywhere in this file. This is a mechanism page, not
   a product page — the visual explains uncertainty narrowing into one
   open testable path, not a product metaphor. */
