/* ============================================================
   Melor case study — page-specific styles.
   The page used to be one tall baked image (me-full.jpg) with absolutely
   positioned overlays. It is now real flowing HTML built on the shared
   case-page system (case-hero / case-meta / case-section / other-projects),
   so everything below only styles Melor's own modules. Spacing comes from the
   shared tokens in styles.css (--gap-section/--gap-head/--gap-block/--gap-card…).
