site/brand/index.html and site/sirius/register.html were still on the old
5-tab layout (Tools · Prometheus · Sirius · Helios · Hermes). Every other
silentmode.st page had already converged on the 6-tab pantheon
(Theseus · Prometheus · Sirius · Hephaestus · Helios · Hermes) via parallel-
session updates. Bringing these two into alignment.
No .X suffix on any label — pantheon labels are bare across the umbrella
site; the .X TLD form is reserved for the future standalone product sites
(theseus.x, sirius.x, hephaestus.x, prometheus.x, helios.x, hermes.x).
Verified live: both pages return the 6 canonical labels in order.
