/**
 * Page styles for /studio/ (the about / trust page — plans/08).
 *
 * Six bands, ink -> paper -> paper-deep -> ink -> paper -> gold, so no two
 * adjacent sections share a ground or a skeleton (Direction §4). The pipeline,
 * team-grid, and client-note LAYOUTS below intentionally mirror the front-page
 * sections/{studio,team,testimonials}.css (which are front-page-only) so the
 * shared vocabulary reads identically here; the card / eyebrow / heading
 * surfaces come from the base cascade and are not repeated.
