/* =============================================================================
   Hopelessly Romantic Films — site stylesheet
   -----------------------------------------------------------------------------
   THE single home for every cross-page element. A page's own stylesheet
   (page-*.css) holds ONLY that page's genuinely unique sections. If a second
   page needs something in here, it reuses these class names verbatim — never a
   re-skinned copy under new names.

   Every value below was measured off the mockups with mockup_probe.py; see
   notes/design-system.md and notes/spec-*.md for the evidence.

   Layout system (confirmed independently by the About, Blog, Portfolio and
   Services specs — one system for the whole site, never a per-page decision):
     outer container   1280px   (x161…x1441 on the 1602 design frame)
     content container 1168px   (x217…x1385) = 1280 − 2×56
     inner padding       56px
     header + marquee are FULL-BLEED with 56px side padding, not the 1280 box
