/* ============================================================
   Dissertation Writing Services USA — clean rebuild
   ONE lean stylesheet. Replaces the per-page huge inline <style>.
   Performance: no render-blocking giant inline block, no <img> hero,
   fonts loaded in <head> with display=swap. Sticky header works
   because NO ancestor uses overflow-x hidden (see note on body).
   Breakpoints: 1050px / 900px / 560px (same as original).
