Single delimited block at the top linking DISPLAY.md and issue mathoudebine#1011;
the rest of the README stays untouched upstream content to keep future
merges trivial.

+> [!NOTE]
+> ## 🔀 About this fork: display platform (carousel / netmap / YAML pages)
+> This fork adds a **multi-page display platform** on top of the stock project — everything is
+> **purely additive** (no upstream files modified) and documented in **[DISPLAY.md](DISPLAY.md)**:
+> * 🎠 **Page carousel** — rotate YAML-defined stat pages (live-reloaded, per-page dwell/refresh)
+> * ⚡ **Diff-based partial rendering** — only changed bands cross the serial link; in-page value
+>   ticks are wipe-free and CPU/RAM stays tiny (~1% of one core, ~30 MB)
+> * 🗺️ **Animated network map** — hosts up/down as a star topology, packet dots on spokes with live traffic
+> * 📊 **Widgets**: `bar`, `metric`, `radial` (traces existing theme ring art — works great over the
+>   stock *Cyberdeck* background), `text`, `graph` (multi-series history), `cores` (per-core mini-bars)
+> * 🔌 **Pluggable data sources** — local psutil values plus named sources (Prometheus implemented),
+>   so pages can show Kubernetes, fleet, or any scraped metric next to host stats
+> * 🌙 Extras: backlight night/away schedule, serial auto-reconnect, net rates with auto units,
+>   RAPL CPU watts, systemd unit
+>
+> Quick start: `venv/bin/python display.py` with `display.yaml` (`mode: standard` runs the stock
+> engine untouched). Proposed upstream in
+> [mathoudebine/turing-smart-screen-python#1011](https://github.com/mathoudebine/turing-smart-screen-python/issues/1011).
+> Everything below this block is the original upstream README.
