Phase A++ — Play Fidelity, In-Play Ranking, and Variant URL Safety
Phase A+ shipped the global nav, the floating in-scroll rank pill, a working `/play` runtime, two seeded per-slide files, and the TOC `[view →]` link — all the surfaces the founder asked for. Day-of smoke-test surfaced three concrete gaps: `/play/pitch/proto/` 404s because the proto variant has no `SLOTS[]` entry yet (the index-redirect was unconditional), the Play runtime doesn't yet have the elegant UI of calmstorm-decks (chrome feels like a dev tool, not a presentation surface), and the `<SlideRankPill>` is mounted in `/scroll` but not in `/play` even though the founder is reading-and-judging slides there too. Phase A++ closes all three without touching Phase A.7's still-blocked publish step, and seeds the calmstorm-primitive lift the larger Phase B will continue.
