English phonics recordings are reused from the existing LearnPlay /phonics/
collection, under CC BY 4.0. Full attribution, contributor names, exact source,
license links and per-file manifest are in /phonics/ATTRIBUTION.txt and manifest.json.
Sounds are unmodified; x and qu are not used in this simple single-sound activity.

Pip's CSS illustration, activity UI and practice-round controls are new LearnPlay
work, not upstream game assets. This is a selected logic/audio adaptation, not
the complete Feed the Monster application. No upstream telemetry, Firebase,
assessment, account or network API integration is included. No endorsement implied.
