content: add ZIP inventory zine illustration

[williamzujkowski]

Adds the missing zine illustration to “One ZIP, Two Lists of Files”: a box contains a ball and key while its inventory depicts only the ball. Gemini via agy generated the drawing; the repository mask tool produces a 55.7 KiB theme-aware PNG. The September 28 publication date is preserved.

Validation: future-preview build and design audits passed; desktop Latte and mobile Dracula screenshots inspected, no horizontal overflow, image HTTP 200, and zero targeted axe AA violations. Independent image/metaphor/markup review found no blockers. Updated the existing review evidence and post hash; the seven-stage report validates READY.

Nexus merge review: real quick-mode supermajority vote approved 3–0 with fail-closed error handling, job job-vote-592daa8e-1fbd-443d-be84-d836ef452017, completed 2026-09-13 18:53:36 UTC, producer 8.49.3. All three roles used gemini-3.1-pro-preview; this is a multi-role review, not independent model diversity. Vote considered supplied evidence; direct image/render checks were performed separately by root and music_pilot.
