+# Fleet — cyber sci-fi secure-bring-up splash (Plymouth "script" plugin).
+#
+# Asset-free on purpose: everything is drawn with Image.Text, so the repo carries
+# no binary images. The dracut hooks drive it with `plymouth update --status=<tok>`
+# (see dot1x-macsec-up.sh / nvmf-connect.sh); this script maps each token to a
+# security-handshake checklist and pulses the in-progress step. Tokens are
+# best-effort and order-independent — anything not reported just stays "pending",
+# and in rd.dot1x=0 test mode the auth/MACsec rows are marked "skipped" (never
+# "failed"). No per-host data is ever shown (only states), per the no-state rule.
