The new tight mark (filled Hermes figure, acid blue, 64×64 viewBox)
replaces both mark.svg and favicon.svg so every existing reference —
brand nav, hero, branding grid, OG image, favicon — picks it up with
no attribute changes. The old file sat behind weird width="5" / "3"
height="22" attributes that crushed it into a sliver; squared the
dimensions per slot so the mark actually renders.
Also drop the "Overview" link from each page's top nav — Hermes.X in
the brand slot already goes to the index, so Overview sent you to the
same place with a different word. Three pages touched: index,
branding, messenger.
