/* NOTE: no light-header override on this page. Re-verified directly against
   the live reference via elementFromPoint on the actual visible nav layer
   (the reference DOM also contains an unrelated, zero-size, pointer-events:
   none decoy nav that reads black — that decoy is not what's rendered).
   The real, visible nav uses the shared default white logo
   (cc_logo_white.webp) and white link color at scroll-top on this page,
   same as every dark-hero page, so no .port-page scoped override is needed. */
