/* ============================================================
   PAGE: Portfolio (full page)
   FILE: assets/css/portfolio-page.css
   Depends on: portfolio-page.html source (pages/trust/portfolio.html),
   surfaces.css, buttons.css, tokens.css, page-header.css,
   breadcrumbs.css, cta-band.css.
   Phase: Stage 9.1 (Group 1 of the Stage 9 Trust & Content batch).

   Namespacing note: this is a DIFFERENT stylesheet/class family
   (.portfolio-page__*) from assets/css/portfolio.css's
   (.portfolio__*), which belongs to the Home "Portfolio / Success
   Highlights" teaser section (Stage 5.6) and is left untouched.
   Keeping a separate namespace avoids any class collision on pages
   where both could theoretically be loaded, and avoids touching a
   protected/completed component.

   Global Card System: `.surface--solid` (surfaces.css) supplies the
   card's white background, hairline border, radius and resting
   shadow — same convention every other card grid in the project
   uses. Only card-specific layout is added here.
