CLAUDE.md's volume paragraph ended "#64 asks for it to be gone on Android outright, which is a platform question the frontend cannot currently ask", which is no longer true -- it can, and the paragraph now says why the answer is a capability rather than a viewport and what that costs. The mediacontrols entry gains the corollary: on that platform "the user's level" is a constant, and the duck is the one thing that may still move the output. NOTES.md carries the measurements: the per-element budget at 424x439 before and after, the :host([hidden]) specificity trap, the fact that the bar's centring survives the control going away, and what no tier here could check.
