/* Content-bank pages.
   Static HTML documents that reuse the SPA's design tokens from styles.css.
   Everything here is layout for long-form reference content — the tokens,
   buttons, .shell, .section, .h-* and .kicker classes all come from
   styles.css so the two surfaces stay visually identical. */
