Every silentmode.st subpage was missing Hephaestus in its topnav, so clicking
Hephaestus from the homepage led to a page whose nav had a different item set —
looked like the header "rearranged and dropped tabs" mid-navigation.
- Add <a href="../hephaestus/">Hephaestus</a> between Sirius and Helios on:
tools, prometheus, sirius, helios, hermes, releases, tlds
- Normalize hephaestus/index.html to use relative paths (../foo/) matching the
convention used by every other subpage — was absolute (/foo/)
- Result: every page has 7 identical nav items in the same order, with
class="here" on whichever section you're viewing. /hephaestus/ keeps its
"Open forge →" CTA appended (an addition, not a reorder).
