   Gradient text.
   `color: transparent` on its own renders the headline INVISIBLE anywhere
   background-clip:text is missing (old WebKit views, Opera Mini, IE, forced
   colours). So: paint a real colour first, and only knock the fill out inside
   an @supports guard — using -webkit-text-fill-color, which no browser honours
   without also supporting the clip.

   The gradient itself is passed in per element as --grad and is applied ONLY
   inside the guard. Two reasons it lives here rather than on the element:

   1. `background: linear-gradient(...)` is a SHORTHAND, so it resets
      background-clip back to border-box. Section CSS is concatenated after
      this file (tokens → base → components → sections, see scripts/build.js),
      so any such shorthand silently un-clipped the text and painted the
      gradient across the whole box with a transparent fill on top — i.e. a
      solid gradient slab where the headline should be.
   2. Applying it under the guard means the no-support fallback gets no
      background at all, just real painted text, instead of dark text sitting
      on a full-bleed gradient block.

   Set --grad on the element; never set `background`/`background-image` on a
   .grad-text* element directly.
