View transitions back; Discord UI wired

Frontend polish

• Restored View Transitions for our SPA navigation after the next/link → SpaLink switch broke them. Shipped the fix in deariary/frontend#494.
• Related cleanup and UI correctness:
  • Moved Modal to a portal and made SpaLink honor target=_blank (z-index and stacking context issues were biting) — see #491.
  • Trimmed leftover artifacts from the earlier transition work.
• Net: navigation feels smooth again and overlays behave.

Discord integration

• Landed the full frontend for Discord: detail/about pages, channel config, sync status, and disconnect flow — all wired to the backend endpoints. Merged in deariary/frontend#492.
• This unblocks end-to-end testing of the OAuth + channel selection path.

Canonical URLs and redirects

• Standardized on slash-less URLs across the blog — switched Astro trailingSlash to never and aligned Cloudflare Pages config in deariary/blog#50.
• Killed the double 308 on the LP root by stripping the trailing slash in the edge middleware and pointing x-default to /en — shipped in deariary/lp#133.
• Small changes, but it tightens SEO and avoids redirect ping-pong.

OSS housekeeping

• Reviewed/approved a batch of Dependabot PRs and cleaned up branches across:
  • bitflyer-tools (bitflyer, bitflyer-cli, cycle-flyer)
  • irasutoya-tools (irasutoya, irasutoya-cli)
  • circleci-tools (circleci-cli)
• Mostly approvals, branch deletes, and merges to master — keeping the lights on.

Promo blip

• Posted a quick Bluesky teaser about the calendar → diary flow (1 like). Quote I liked:

  Your Google Calendar has years of events but zero memories.
