/* -----------------------------------------------
   PATTERNS: valencia/query-cards, valencia/query-cards-lead

   One card, two photo treatments, chosen by a modifier on the wrapper:
     .valencia-qcards--fade   photo fills the card, colour fades up
     .valencia-qcards--plate  solid colour, photo as a corner plate

   THE ARCHITECTURE. Core's post-featured-image block renders NOTHING
   when a post has no featured image. That is the entire conditional —
   no PHP, no has-image class, no fallback markup. So the card is always
   the colour field with its title, complete on its own, and the photo
   is a layer that simply is not there for the 19 of 51 posts without
   one. Nothing degrades, because the no-photo card IS the base state.

   THE ONE DEPARTURE FROM THE THEME'S RULE. Card colours are assigned
   here by :nth-child, not as block attributes, so they cannot be
   changed in the editor sidebar. Query Loop renders ONE template N
   times — there is no per-card markup to hang an attribute on, so a
   cycling palette is only expressible in CSS. The colours are exposed
   as custom properties on the wrapper (--qc-1 … --qc-4) so a page can
   override the set in one place without editing selectors.

   Why cycle by position rather than map to category: 23 of 51 posts
   are Uncategorized and there are 12 categories against ~5 usable
   colours, so a category map would paint nearly half the grid one
   colour and scatter singletons through the rest. Position claims no
   meaning and always balances.

   Everything else IS a block attribute: post counts, offset, order,
   columns, the grid gap, and the spacing on every element.
