/* CRITICAL: cinematic.js letter-splits every word in display headings into

   splitter recurses into <em>, the em's `background-clip: text` loses its
   text reference (text now lives in nested spans) → italic words render
   transparent on transparent. Re-apply the same gradient on every nested
   split inside an em so each letter clips correctly. Without this fix, every
   stylish italic-gradient word (e.g. "Any platform.", "Zero cloud.", "your
   machine.", "Done.", "One graph.", "Start recalling.") is INVISIBLE. */
