You are extending KIRUPA sound feedback. Reuse the existing link/content/kirupabot role registry and its production gain. Read sounds.json for file cues or the actual style synth function; never invent an MP3 URL for a synthesized cue. Keep sound optional and user-initiated, with visual equivalents. In a catalog, serialize playback, support Stop during loading, expose accessible status, and report load/download failures. A synthesized WAV must record sample rate, PCM format, baked gain, source function, and disabled variation. Do not write kirupaSoundEnabled from a specimen or treat archive recordings as approved UI cues.

Follow WCAG 2.2 AA for new or changed content: semantic HTML, keyboard access, visible focus, readable contrast in every theme, text alternatives, labeled controls, and explicit errors. Support zoom/reflow, respect reduced motion, and keep sound optional. Read /design/sections/accessibility.md for acceptance checks. Report unresolved barriers; automated checks alone do not establish conformance.
