- Extract the logo into an inline-SVG LogoMark shared by the loader and
the site logo; one CSS animation driven by `.is-animating`
- Hovering/focusing the logo redraws it from a faint ghost and runs one
wave along the facets; a replay always finishes and can't restart
midway; skipped for reduced motion
- Cap hero subtitles (inner pages + home intro) at 36rem with pretty
wrapping so the About hero no longer runs across half the screen
