   Vinyl Standard — shared site stylesheet
   ============================================================
   Loaded by every page on the site. Contains the canonical
   color palette, typography, nav, hero, and footer rules.
   Page-specific styles live in the page's own <style> block.

   When adding shared rules, edit ONLY this file. Do not edit
   the duplicate copies that still live in some pages' inline
   <style> blocks; those will be cleaned up in Phase 2.
