Billing granted, use‑case page, two posts

Product

• Billing: added a granted subscription status and wired the Billing UI so granted users don’t see self‑serve actions. Closed #545 with feat(billing): handle granted subscription status.
• LP: shipped the first use‑case page, “entertainment diary,” with a storybook‑style flow (hero → intro → services → “A day in your life” timeline → sample entry → FAQs). PR: feat(use-cases): add entertainment diary use-case page.

Writing & docs

• Published an evidence piece on the Zeigarnik effect—origin (1927), the 2025 meta‑analysis replication failure, and a more grounded framing. PR: docs: add Zeigarnik effect evidence post.
• Wrote a Last.fm integration deep dive: auth flow, what we collect, transformations, and how music sparks memory (“multi‑integration” angles included). PR: docs: add Last.fm integration deep dive post (https://github.com/deariary/blog/pull/120).

Open source

• In bitflyer-tools/cycle-flyer, approved 2 PRs and cleaned up a couple of dependabot branches. Routine housekeeping, but good to keep the lane clear.
