fix(marketing): header logo iPhone clipping + use shared SVG asset (#4)

* fix(marketing): header logo iPhone clipping + use shared SVG asset

- Logo.astro imports the existing pywire-mark.svg as an Astro SVG
  component instead of duplicating the path inline. Single source of
  truth; SVG still inlined into HTML at build (currentColor theming
  preserved).
- Glyph viewBox widened from "37 47 133 191" to "35 41 138 202": path
  coords reach y~43, y~239, x~170.66 — the old viewBox subpixel-clipped
  the top and bottom of the P on Mobile Safari.
- .logo-mark CSS sizing changed to width/height 100% so iOS Safari has
  explicit dimensions to render against (the old auto+100% combo was
  unreliable on iOS without explicit width/height attrs on the SVG).

* fix(marketing): strip color attr from pywire-mark.svg so logo inherits accent

The shared SVG carried a hardcoded color="#1d3df0" attribute, which
sets the element's own currentColor and overrode the parent CSS
.logo-mark { color: var(--accent-color) }. Result: the P glyph rendered
in blue instead of the cyan accent. The previous inline copy didn't have
this attr, so the regression only landed when the component switched to
importing the shared file.
