Replaces the shared @ferrlabs/ui-astro/Footer (4-equal-cols, generic SaaS) with a local Footer.astro matching the editorial design:
- Left brand column with 40px logo, Fraunces 900 wordmark, italic colophon, 4 product chips (FerrFlow gets a soft glow because it’s live).
- Right link columns: Products / Resources / Company / Legal with mono uppercase headers.
- Bottom strip: copyright on the left, green dot + “All systems normal · ferrlabs.com” on the right.
- Stacks cleanly on mobile (brand on top, link cols become 2x2).
