/* ==========================================================================
   The Deep Dive: newsletter archive + issue pages (Deploy 13.1)
   --------------------------------------------------------------------------
   Kept in its own file on purpose. The CloudFront CSP allow-lists inline
   <style>/<script> blocks by SHA-256 hash and does not allow inline style=""
   attributes, so every rule for the newsletter pages lives here (served
   from 'self') and the page markup only uses classes.
   Root font-size is 62.5% (theme.css), so 1rem = 10px.
