   CPSM — ScienceDirect-style overlay on OJS Default Theme
   Conference Proceedings in Science and Management
   
   PHILOSOPHY: This is an OVERLAY, not a layout rewrite.
   OJS default theme handles structure, spacing, sidebar positioning.
   We only restyle: colors, typography, small accents.
   
   Accent: SHORAM copper (replaces Elsevier orange)
   Editorial production: SHORAM
