Three captured exhibits (keymaps-style, dense captions), via a reproducible playwright capture script (figures/capture-figures.mjs): - Fig 2: YouTube's 2026 playback-speed control — the coarse itemized menu. - Fig 3: the AC dj piece — a scratchable record on a screen with no record. - Fig 4 (full-width): Spotify's own Idea Exchange — 666 votes for "any speed control for music," status "Not Right Now," marked Case Closed. Demand and the structural refusal in one frame; the caption keeps the reason open (licensing / artist relations / deprioritization — the platform doesn't say).
