/*
 * Codex OpCo projects: the fanned project cards, the kind filter and the modal.
 *
 * The rules are the codexcorp.ca / anuragbains.com projects section, minus the
 * shelf. Every colour, face, radius and shadow is a --pc-* token, so each OpCo
 * keeps this file unchanged and themes it in its own projects.html:
 *
 *   --pc-ground       the modal's own ground        --pc-card     a card at rest
 *   --pc-raised       a card on hover, the gallery  --pc-text     headings
 *   --pc-text-mid     body copy                     --pc-text-low quiet labels
 *   --pc-hair         card and divider lines        --pc-hair-2   control borders
 *   --pc-edge         a control on hover            --pc-signal   the accent fill
 *   --pc-signal-ink   the accent as text            --pc-on-signal text on the fill
 *   --pc-shot-frame   the hairline round a screenshot
 *   --pc-f-display / --pc-f-body / --pc-f-mono      the site's three faces
 *   --pc-name-case    none or uppercase              --pc-name-weight
 *   --pc-radius       card and modal corners        --pc-radius-sm controls and shots
 *   --pc-border       card border width             --pc-shadow / --pc-shadow-hover
 *   --pc-lift         how far a card rises on hover
 *   --pc-top          optional: the card's top edge (default a 2px accent rule)
 *   --pc-art-ground   optional: the ground behind a drawn diagram (match the SVG's own)
 *
 * Template: 2. Tooling/templates/project-cards/projects.css. Edit there, then copy.
