All checks were successful
Check / eval (push) Successful in 3m3s
Hovering the clock now leads with the zone — "{:%Z (UTC%z)}" above the
calendar — on the generated bar and both summer whole-swaps (parity).
Under auto-timezone the existing tz-watch SIGUSR2 reload keeps it
showing the currently detected zone. %Z is the abbreviation (BST), not
the IANA name — strftime has no code for that, and it satisfies the
"(optional)" nicety.
Verified: V0; V1 — the rendered generated config carries the new
tooltip-format and both summer jsonc parse with it. Hover render
queued for hardware.
