fix(theme): blog posts no longer fade out; readable post layout

- Scroll reveal used threshold 0.15: a section taller than ~6.7 screens (a
  long article) never reached it, so after the reveal class hid it, it
  stayed hidden. Reveal as soon as any part enters (threshold 0).
- Post header: full-width title with meta below and a normal gap
- Article: heading sizes per level, photos keep their shape (no crop),
  icon-sized inline SVGs, full-width embeds
- Strip the imported 'Home' breadcrumb line from posts and card excerpts
- Theme 1.0.15
