/* =========================================================================
   .er-relation — the shared relationship primitive.

   One styling vocabulary for how Eternal Roam presents relationships between
   saints, places, relics, routes, and cities. Scoped entirely under .er-relation
   and built on the global --er-* tokens, so it resolves the same on a saint-v1
   page, a place-v1 page, or anywhere else it is later adopted.

   Modes:  --cards (image-led)  --rows (compact)  --list (text-only)
   Density: --dominant / --compact realise the page demotion rule.

   No grey placeholder slot exists anywhere in this file: a card without an image
   falls back to a textured, inked monogram plate (--plate--monogram), and a set
   with no image is rendered as --list by the PHP primitive before it reaches here.
