   THE WORDMARK
   ----------------------------------------------------------------------------
   A gradient that cycles through the accent. It is the one piece of pure
   decoration in either product, so it has to earn its place and stay inside
   the design contract:

   - It is ONE accent, not a rainbow. Every stop is a step of --brand that
     already exists in tokens.css (300, 400, brand, 600, and the sky tints),
     so it reads as the Nimbus blue moving rather than as a second colour
     arriving. AGENTS.md section 4 rule 1 survives.
   - It animates `background-position`, not the gradient itself. Animating
     colour stops re-rasterises the gradient every frame on the main thread;
     sliding an oversized background is cheap and smooth.
   - 8 seconds, linear, infinite. Slow enough to read as a shimmer rather than
     a flash, and nothing in the page depends on where in the cycle it is.
   - It STOPS DEAD under prefers-reduced-motion, falling back to a static
     gradient. Rule 7: everything collapses. A looping animation behind text is
     exactly what that setting is for.
   - Fallback colour first, so a browser without background-clip: text shows
     solid brand rather than invisible text. That failure mode is total, so it
     is worth the two extra lines.
