/* ============================================================
   ZINO AVIATION — SECTION TYPE SCALE
   Dara: "make sure that all sections in all pages have the same
   font and font size for the main header, sub header and the body
   copy for each section so there's similarities. This does not
   affect the title cards."

   One rank per role, declared once. Loaded LAST on every page so
   it always settles the cascade — style.css, pages.css and
   type-luxury.css had each grown their own section sizes and they
   had drifted apart (h2 ran 36px to 56px, sub headers 15px to 39px,
   body copy 14.4px to 18px depending on the page).

   Card type is deliberately untouched: .principle-card, .service-card,
   .acq-bento-card, .acq-point-card and friends keep their own sizes.
