   Contrast + colour polish pass (2026-10-31)
   Problem: several phpwind defaults assume a dark-blue chrome, but the
   archive overlay repainted those bars to pale paper, so their white /
   near-white text lost its background and became unreadable. This section
   repairs those spots and unifies the remaining blue accents to brass.
   Layout (margins/padding/widths) is untouched.
