1.67.1 (2026-07-24)

Bug Fixes

• docs: recolor helix and zellij home-page logos to brand purple

• replace the two off-brand home-page hero icons with purple
  renderings of the official upstream logos: the helix ribbon is a
  monotone #5555ff with its back-twirl outlined, and the zellij
  hexagon badge is rendered in purple monochrome
• square both icon viewBoxes so the logos sit on a consistent grid
  and align with the surrounding hero tiles
