/* EnDepth borders. The system is line-led: hairlines everywhere, a 2px ink rule
   above every section header, a 3px or 4px accent edge to flag emphasis.
   No border-radius-plus-coloured-left-border decoration on ordinary cards — the
   accent edge is a signal, used only on callouts, status cards and the pull quote. */
