 * APU Essay Review · engraved opening plaque.
 *
 * Styles the markup the essay review filter builds from
 *   {{opening: ...}}  → figure.fg-engraved.fg-engraved--opening
 *   {{opening_cta}}   → p.fg-engraved__cta (inside the plaque) or
 *                       div.fg-engraved.fg-engraved--solo (on its own)
 *
 * CSS only: wood, frame, corner scrolls, quotation marks and the burned-in
 * text effect are all gradients, borders and generated content. No images,
 * no JavaScript.
 *
 * Specificity: the theme styles body copy with
 *   .node__content figure              { margin: 32px 0 }        (0,1,1)
 *   .node__content .field--name-body p { max-width: 65ch }       (0,2,1)
 *   blockquote                         { border-left: 3px gold } (0,0,1)
 * and theme CSS loads after module CSS, so a tie goes to the theme. Every
 * rule here is scoped as .fg-engraved .fg-engraved__plaque … (0,3,x) or
 * .fg-engraved.fg-engraved (0,2,0) for the root, which beats those rules
 * without !important.
 *
 * Fonts: Great Vibes (the two quotation marks only) and Cormorant Garamond
 * Italic (body text: Latin, extended Latin, Vietnamese), both SIL Open Font License,
 * self-hosted in css/fonts so the strict CSP (font-src 'self') needs no
 * external domain. Licenses sit beside them.
