+# Anthias Player — Silent Boot Setup
+# Runs on the Pi HOST (not inside containers).
+# Idempotent: safe to run multiple times, patches only once.
+#
+# What it does:
+#   1. Disables rainbow splash & firmware boot delay
+#   2. Silences kernel output (quiet, no logos, no cursor)
+#   3. Redirects console from tty1 to tty3 (invisible)
+#   4. Disables login prompt on the display (getty@tty1)
+#   5. Installs fbi and creates a splash service that shows
+#      the Anthias standby image immediately on boot
+#
+# Usage:
+#   sudo bash bin/setup_silent_boot.sh
+#
+# A reboot is required after the first run.
+# ──────────────────────────────────────────────────────────────
