/* ============================================================
   CPSM custom stylesheet, version 2.0, 27 September 2026
   Conference Proceedings in Science and Management
   SHORAM Editorial Services

   Overlay on the OJS Default Theme. The default theme handles
   layout; this file sets color, type, tables, and the footer.
   Uploaded under Settings, Website, Appearance, Journal style sheet.

   Changes from the 6 May 2026 file:
   - footer grid set to four columns to match the footer HTML
   - content tables: full width, padding, row headers, phone scroll
   - static page titles styled (the old .static_page rules matched nothing)
   - visible keyboard focus on links, buttons, and form fields
   - small copper text and copper buttons moved to the darker
     brand copper for WCAG AA contrast
   - comments cleaned of third-party names and stale examples
