- New article (Week 1): blog/what-happens-to-your-bitcoin.html, built on
the existing it-all-starts-with-the-seed.html template/layout.
- Cover image: blog/img/what-happens-to-your-bitcoin-cover.webp (1600x900,
WebP, ~76KB).
- blog.html: add the new post card at the top of the index (newest-first).
- blog.html: fix .post-card thumbnail crop -- object-fit:cover was cutting
off image edges/text with no margin; switched to object-fit:contain with
16px padding and a white frame so the full thumbnail is visible on all
cards.
