% Theme-local semantic palette.
%
% Page blue belongs to page structure and never becomes ordinary running-text
% emphasis. HUSTBlue preserves the official reference color for compatibility;
% HUSTFrame* owns page fields, while the reference-derived box blue is a
% separate component accent confined to semantic title bands.
