/* 
   The tag's inline color sits on .post-tag. The standfirst needs to inherit it
   for border-bottom-color via currentColor. We achieve this by setting the
   standfirst's color to inherit from a wrapper, or by using a sibling approach.
   Since .post-tag and .post-standfirst are siblings inside .post-header, we
   use a CSS trick: the .post-header inherits the inline color set on .post-tag,
   which then flows to .post-standfirst's border via currentColor.
   
   However, since inline styles only apply to the element itself, we use a 
   different strategy: we set the standfirst's border-color to inherit and
   the .post-tag's color will influence via CSS custom property.
   
   Practical approach: The border uses the tag color via a JS-set custom prop,
   OR we use this cascade trick where the standfirst border inherits. Since the
   inline color is only on .post-tag, we need JS or template support.
   
   Fallback: Use a subtle grey border, and if the template passes the accent
   colour as a CSS variable on the header wrapper, it will work.
   
   Best CSS-only approach: Use .post-tag's color to set a custom property
   via the 'color' property, and use currentColor for the border on a pseudo-
   element positioned under the standfirst.
   
   ACTUAL SOLUTION: We style .post-header to use color: inherit, and the
   template can pass the accent to .post-header's style. But per the brief,
   the inline color is only on .post-tag.
   
   PRAGMATIC SOLUTION: Since .post-tag has inline color, and .post-standfirst
   is a sibling, we cannot inherit via CSS alone across siblings. Instead:
   - Default border: var(--fi-cyan) as a tasteful fallback
   - If the template author adds style="color: X" to .post-header or 
     .post-standfirst directly, currentColor will pick it up automatically.
   - We document this for the theme developer.
