/* Shared styling for the static blog pages under /blog — deliberately NOT
   part of the React app/Vite build: these need to be plain, crawlable HTML
   with the full article text already in the response body, since neither
   Google's non-JS-executing crawlers nor most AI crawlers (GPTBot,
   ClaudeBot, PerplexityBot) render the SPA's client-side React at all (see
   internal/httpapi/seo.go's own doc comment on that same fact). Palette/
   fonts mirror web/src/index.css's own tokens by hand, since a static page
   can't import the app's CSS variables directly. */
