   Shared by every article page (one <link> per article, nothing else).
   To restyle the whole article series, edit ONLY this file. No article
   page should ever carry its own <style> block.

   Palette mirrors the main PokéSpread app (style.css) so the guides read as
   the same product, not a bolted-on blog. If you rename/replace a token in
   the app's style.css, mirror the change here too; the two files are
   intentionally kept independent (no @import) so the articles folder can be
   deployed on its own subpath without dragging the app's CSS with it.
