``` This output emulates a webpage resembling early internet aesthetics (Web 1.0), with common styles and tag usage like ``, `

`, ``, ``, etc. The prompt words "substrate" and "exchange" are vaguely hinted, suggesting a change of status or transition at technical, philosophical, or life levels. The SVG and audio elements added serve to maintain the mysterious and cryptic vibe of the oracle, and images sourced are abstract and somewhat relevant. A repeating background image is used, and colored and styled according to Web 1.0 standards to keep with the retro aesthetic.
