/*
 * Home page layout (src/pages/index.astro).
 *
 * Structure — "bezel and display field":
 *
 *   header (black)
 *   hero (black bezel, compact and content-sized: no viewport minimum)
 *   ╭─ field ───────────────────────────────────────────────╮  lighter
 *   │ What we build · Featured work · How we work ·          │  phosphor
 *   │ Products · Capabilities                                │  gray-green
 *   ╰────────────────────────────────────────────────────────╯
 *   CTA band + footer (black shell again)
 *
 * The hero is deliberately short so the field's top edge and the What we
 * build columns are visible on the first desktop screen; the layout itself
 * says "the page continues", with no scroll prompt. Inside the field,
 * sections share one surface, are separated by thin rules, and most use a
 * "rail": section identity in a narrow left column, content beside it, so
 * there are no empty heading rows.
 *
 * The shared page shell (shell-page base, display field, field sections,
 * rail, work grid, closing band on black, scroll reveal) and all reusable
 * components live in system.css; this file only composes Home's own
 * sections (hero, What we build, method note, product grid, capabilities)
 * and the hero motto motion.
