/**
 * Case-studies portfolio: category tabs, grid and lightbox.
 *
 * Ported from a standalone portfolio page. Two things had to change for it to
 * live here:
 *
 * 1. Everything is scoped under `.wp-portfolio`. The source stylesheet used
 *    bare class names (.tab, .port-card, .lightbox) that would collide with the
 *    rest of the site, and this page sits inside `.about-scope`, whose legacy
 *    rules - `.about-scope a { color: #000 }`, `cursor: none`, its own button
 *    styling - reach anything unscoped.
 *
 * 2. The source ran on a light theme driven by variables from its own style.css
 *    (--ink, --muted, --bg, --font-d). Those are restated at the top of this
 *    file against this site's dark palette and Outfit/General Sans instead, so
 *    the block reads as part of this site rather than a pasted-in page.
 *
 * Loaded only by portfolio.php.
