/* ==========================================================================
   PB Projects Grid Block
   .pb-section-pb-f-projects-grid
   Responsive 2 / 3 / 4 column grid of project tiles pulled from the
   pb_projects CPT. Header (intro left, optional link button right), optional
   front-end category + country filters, then a grid of translucent tiles:
   featured image (16:9) + title + blurb, the whole tile linking to the project.

   COLOUR DERIVATION: like pb_f_cards / pb_f_team_grid, the section background
   (`.pb-section.bg-*`) determines the tile colours. The section's own
   text/heading/link is derived globally in pb-section-bgcolors.css (§4.0 G2);
   the tile surface + tile text are derived HERE, scoped per section ground,
   because G2 does not cover nested tiles. Figma ground is teal (#09414e), with
   tiles at rgba(0,44,53,0.5) (teal-dark @ 50%).
