v1.2.0 — the 24-hour tape

Every card so far asks how much you ship. This release asks when —
and hands down a diagnosis. Existing embeds are untouched.

The Holter monitor

• /holter/<user> — your circadian rhythm as a 24-hour histogram of
  recent public activity, stamped with a verdict: NOCTURNAL, EARLY BIRD,
  DAYWALKER, AFTER HOURS, or ARRHYTHMIC when there's no pattern at all.
• SUSPECTED SLEEP — the monitor finds your longest quiet stretch and
  prints it as your sleep window. No quiet stretch? not observed, which is
  its own diagnosis.
• Pass tz=<utc-offset> (e.g. tz=3.5) so the verdict lands on your local
  hours — GitHub timestamps are UTC. All 13 themes and layout params apply;
  theme=phosphor&scanlines=1 looks like actual hospital equipment.
• Share the verdict — /s/YOU/holter unfurls on Twitter/Discord/Slack
  with your histogram and diagnosis stamped on the preview image.
• GitHub Action: new holter: input. The v1 tag has moved, so workflows on
  @v1 get it automatically.

The builder explains itself

• Live demo preview — the empty builder now renders a demo card that
  reacts to every click: switch modes, themes, shapes, waves, scanlines and
  watch it repaint before you've typed a username (/demo/<mode> under the
  hood — synthetic patients, zero GitHub API calls, never counted in stats).
• Every mode chip carries a plain-words blurb — no jargon, no guessing what
  a "ward" is.
• /#holter deep-links straight into holter mode; the hero points there.

Everything else

• The landing page now shows the terminal CLI (npx github-pulse-cli) —
  which is live on npm.
• Redis client also accepts the KV_REST_API_* env names the Vercel
  marketplace Upstash integration injects.

v1.1.0 — the ward opens

Built in the 24 hours after launch. Existing embeds are untouched — every
change to current cards is invisible or strictly better.

New card types

• Ward cards — /ward/a,b,c: 2–6 users on one monitor, triage-sorted by
  bpm, traces colored by life state, N/M ALIVE pill.
• Cardiology report — /report/<user>: the annual checkup. Year-long EKG
  strip, active days, longest streak, longest flatline (dated), busiest day,
  weekend load. theme=paper makes it a printout.

New surfaces

• Wall of Hearts — /wall: live gallery of recently beating cards.
  Strictly opt-in: add wall=1 to your own embed to join; rendering
  someone else's card never publishes them. Proper og-image for sharing.
• Dead man's switch — POST /api/watch {login, url} pings your Discord or
  Slack webhook when a watched user flatlines or revives (daily sweep).
  Opt out of being watchable at all: POST /api/watch/block.
• Defibrillator — critical/flatlined share pages grow a paddle-charging
  button that broadcasts a prefilled code blue. Preview your own death page:
  /s/YOU?state=flatline.
• Terminal CLI — npx github-pulse-cli <user|owner/repo>: the vitals as
  an ASCII EKG, zero dependencies.
• Hearts counter — /api/stats: anonymous aggregate of cards served.

Reliability

• Shared vitals cache — one GitHub API call per subject per cache window,
  across all param variants (GraphQL calls were previously uncached).
• Stale-on-error — rate-limit spikes serve slightly-old vitals instead of
  an error card.

Everything else

• Landing page redesigned as a hospital monitor; builder gained ward/report
  modes and a wall opt-in checkbox at the embed snippet.
• GitHub Action: new ward: and report: inputs.
• ?v= cache-buster documented; README samples for ward + report.

Self-hosters: set UPSTASH_REDIS_REST_URL/TOKEN to activate the record,
counter, wall, and watches; CRON_SECRET locks the sweep;
PULSE_WEBHOOK_ALLOW_ANY=1 allows webhook targets beyond Discord/Slack.
