/* ============================================
   MINIMAL RESET
   Kill browser defaults that fight token-driven spacing.

   Layered into @layer reset (v3 master defines the layer order) so these
   defaults lose to master's component rules, as a reset should. Unlayered,
   they beat EVERY @layer rule — e.g. `svg { display: block }` overrode
   .site-nav__caret's `inline-block` (nav chevron wrapped below its label)
   and `h1-h6 { margin-top: 0 }` overrode master's prose heading spacing.
   Kept (rather than deleted) for consumers pairing theme-layout with a
   pre-v3 master that ships no reset of its own.
   ============================================ */

   CONTAINER (modernized v3.7.2)
   ============================================
   Pre-v3.7.2 this rule used `width: 85%` + a max-width with a mobile
   @media bumping to 90%. That was the legacy WordPress / Divi pattern
   — proportional gutters that varied with viewport width. It made
   .container diverge from master's own .site-nav__inner (which uses
   `max-inline-size + padding-inline + margin-inline: auto`), so
   nav-and-section content edges never aligned except by accident
   at ≥1400px viewports.

   v3.7.2 switches .container to match master's canonical pattern:
   max-inline-size + fixed padding-inline. Result: .container and
   .site-nav__inner content edges align at every viewport. Fixed
   gutter behaviour is the modern norm (Stripe, Linear, Vercel,
   Tailwind defaults). Drops the mobile-bump @media — `padding-inline`
   at a constant 1.5rem already gives sensible mobile gutters.

   Token fix: --layout-max-width was a non-existent token (fallback
   1400px was what actually resolved). Master's canonical name is
   --layout-max. Fixed while we're here.

   Breaking-change note: any consumer that relied on the previous
   85%-proportional-gutter behaviour will see narrower content +
   wider gutters at non-1400px viewports after this change. Project-
   layer override to recover the legacy behaviour:
     @layer overrides {
       .container { width: 85%; padding-inline: 0; }
       @media (max-width: 768px) {
         .container { width: 90%; }
       }
     }

   v3.16.0: master now ships the canonical .container (section 40.0,
   same metrics, gutter tokenized as --space-md). This copy stays for
   consumers pairing theme-layout with an older master; keep the two
   in sync if either changes.
