/**
 * SPD Hero — Homepage hero section
 * =====================================================================
 * Phase 3a component styles. Reproduces the React Hero (HomePage.tsx) using
 * the centralized SPD design system for typography/radius/shadow/spacing
 * tokens, and React-reference-exact brand colors scoped to .spd-hero.
 *
 * The React site is the visual source of truth. The global SPD tokens
 * (--spd-blue/red/gold) intentionally differ slightly from the React
 * reference hexes; to match the React render pixel-for-pixel without
 * polluting the global token system, the Hero defines its own scoped
 * brand-color variables below. Neutral slates are used as raw values,
 * consistent with spd-shell.css. The warm hero surface is a section-
 * scoped decoration (not a global palette addition).
 *
 * Loaded after spd-shell.css.

/* ----------------------------------------------------------------
   Escape Astra's boxed content container on the front page.
   On the SPD front page, Astra wraps <main> in `.ast-container` which is
   given `display:flex; flex-direction:column-reverse; width:100%` and
   `padding:0.54em` (rules keyed on the #content ID — specificity 1,x,x).
   Astra also adds `padding:20px` to `.site-main`. These constrain the
   Hero and break its full-bleed right-side image.

   The Hero's right-side image must be full-bleed (edge to edge), so we
   neutralize the container's flex/padding and the main's padding. We use
   `#content` in the selector to beat Astra's ID-based specificity, scoped
   to body.spd-front-page so no other Astra page is affected. The Hero's
   internal `.spd-container` provides the 1280px content width for the
   text column. No Astra file is modified.
