- Prepend attribution comment to "Copy all" exporter clipboard
- Show inline ⭐ Star nudge on individual rule copy (3s, dismisses automatically)
- Change StatsBar stars label to "engineers starred" for social proof
- Add milestone progress bar toward 10k stars in StatsBar
- Fix header/StatsBar showing "0" when SSR GitHub API fetch fails (use "—" placeholder)

feat: refine star toast — brand orange, idle trigger, 15s auto-hide 
- Style: brand orange background with white text (visible on any bg)
- Trigger: every 5 copies OR after 10 minutes of inactivity on page
- Auto-hide: 15s (reset if toast re-triggers before expiry)
- Idle timer resets on each copy

feat: add star nudge toast after every 5 rule copies 
Show a dismissible toast (bottom-right, 20s auto-hide) nudging users
to star the GitHub repo. Fires every 5 copies via a sessionStorage
counter. CopyButton dispatches a copy-success custom event; StarToast
listens for it and manages display logic.

fix: replace invalid top-level return with isFresh flag in star scripts 
Top-level return is a syntax error in ES modules. Replace the early
return pattern with an isFresh boolean guard. Also revert the hero
"Star on GitHub" button change.

feat: add GitHub stars to StatsBar and fix cache early-return 
Add a 4th stat (⭐ GitHub stars) to StatsBar with build-time fallback
and live client-side fetch. Both Header and StatsBar share the same
sessionStorage cache key and skip the API call when the cache is fresh
(1h TTL), reducing fetches to at most one per session.

feat: replace GitHub icon with Star button and live star count 
Replace the plain GitHub icon+count in the header with a proper two-zone
star button (★ Star | 8.4k). The count is seeded at build time from the
GitHub API and refreshed client-side on page load with a 1-hour
sessionStorage cache.

build(deps): migrate from @astrojs/tailwind to @tailwindcss/vite for Tailwind v4 (#547) 
@astrojs/tailwind v6 still requires tailwindcss@^3; replace it with the
official @tailwindcss/vite Vite plugin. Update global.css to v4 syntax
(@import "tailwindcss", @custom-variant dark, @theme tokens) and drop
the now-unused tailwind.config.mjs.

feat/astro migration (#538) 
* feat: migrate website from Jekyll to Astro

Rebuilds the site using Astro (SSG) with Tailwind CSS v4, replacing the
Jekyll/Cayman theme. Key changes:

- Splits the monolithic /rules page into 110 statically-generated pages
  (92 per-service + 13 group index + homepage + guide pages) for SEO
- URL structure: /rules/[group-slug]/[service-slug]/ with backward-
  compatibility redirect map for old anchor-based URLs (/rules#redis)
- Modern UI: Prometheus-orange accent, dark mode (system + toggle),
  sticky sidebar, responsive layout, copy-to-clipboard per rule/section
- SEO: per-page <title>, <meta description>, Open Graph, Twitter Card,
  canonical URLs, sitemap.xml via @astrojs/sitemap
- GEO: FAQPage JSON-LD schema on each service page (rules as Q&A pairs
  for AI search engines), TechArticle schema, BreadcrumbList
- Search: Pagefind (build-time index, lazy-loaded, ~200KB)
- Zero JS by default; copy buttons and theme toggle use inline scripts
- New CI: .github/workflows/deploy.yml builds Astro + Pagefind and
  deploys to GitHub Pages via actions/deploy-pages
- Existing dist.yml and test.yml workflows are untouched
- _data/rules.yml remains the single source of truth

Note: GitHub Pages source must be changed from "Build from branch"
(Jekyll) to "GitHub Actions" in repository settings.

* doc: new website based on astro

* refactor: remove previous website

* chore: add npm dependabot for Astro site + scope CI to _data changes

* Update site/astro.config.mjs

* fix: strip trailing slash from BASE_URL to prevent double slashes in URLs

Co-authored-by: samber <2951285+samber@users.noreply.github.com>

* fix: resolve Astro build errors in astro.config.mjs

- Remove assetsInclude yml which caused Vite to treat YAML files as static assets instead of running them through the custom YAML transform plugin; data.groups was undefined at runtime because the import resolved to a URL rather than parsed content
- Deduplicate old-path redirects: emit only the slash-less variant per service to avoid Astro router collision warnings (trailing-slash variant is handled automatically)

- Thanos: filter gRPC errors to actual error codes only (drop NotFound, Cancelled, etc.)
- Loki/Promtail: fix histogram_quantile to aggregate by (namespace, job, route, le)
- Mimir: raise rate()>0 thresholds to >0.05, add missing for: durations
- OTel Collector: raise rate()>0 thresholds to >0.05, add deprecation comments

fix/promql rules review (#533) 
* fix(data): comprehensive PromQL review across all ~937 rules

Query fixes:
- Replace rate()/increase() with deriv()/delta() on gauge metrics exposed
  as untyped by exporters (node_vmstat_oom_kill, mysql_global_status_*,
  systemd_socket_refused_connections_total)
- Fix Ceph OSD latency metric name: ceph_osd_perf_apply_latency_seconds
  → ceph_osd_apply_latency_ms (Ceph MGR Prometheus module)
- Fix NATS subscriptions metric: gnatsd_connz_subscriptions (per-conn)
  → gnatsd_varz_subscriptions (server total)
- Fix Caddy reverse proxy down query: count()==0 → direct gauge == 0
- Fix RabbitMQ total connections metric: connectionsTotal → connections
- Fix Cilium ClusterMesh/KVStoreMesh: deriv() on failure gauge → direct
  gauge comparison (deriv > 0 misses stable non-zero failure states)
- Fix cert-manager ACME metric name: certmanager_http_acme_client_request_count
  → certmanager_acme_client_request_count (renamed in v1.19+)
- Fix Thanos Query gRPC filter: grpc_code!="OK" → explicit error codes
- Fix Flink duplicate comments: field (YAML last-write-wins bug)
- Add datid!="0" filter to PostgreSQL dead locks query
- Fix PostgreSQL high rollback rate: restructure division-by-zero guard
  and move ratio calculation outside sum()
- Add division-by-zero guards: Container Low CPU, Hadoop ResourceManager
  memory, Hadoop HBase heap, Vault cluster health
- Add for: 1m to Blackbox probe failed/HTTP failure and Ceph State/
  OSD Down/PG unavailable

Threshold fixes:
- Replace > 0 with meaningful thresholds on rate()/increase() queries
  across: Alertmanager, eBPF decoder errors, systemd refused connections,
  Memcached, Cassandra (Instaclustr + Criteo), ClickHouse distributed
  inserts, CouchDB log entries, HAProxy healthcheck failures, RabbitMQ
  unroutable messages, Spinnaker, Cilium, Mimir TSDB/alertmanager,
  OTel Collector receiver refused metrics
- Fix Elasticsearch High Indexing Latency threshold: 0.0005s → 0.01s
  (0.5ms was below normal operating range; 10ms is more realistic)

Description fixes:
- Fix MySQL slow queries: remove duplicate "mysql" word
- Fix SMART device description: remove trailing stray ")" (6 rules)
- Fix host disk IO description: remove duplicate "Check storage for issues."
- Fix EDAC correctable errors: "last 5 minutes" → "last 1 minute"
- Fix EDAC uncorrectable errors: remove time-window claim (raw counter)
- Fix Mimir store-gateway sync description: said "10 minutes" but
  threshold is 1800s (30 minutes)
- Fix Vault description false "%" suffix on count values
- Improve descriptions across RabbitMQ, Zookeeper, Kafka, Pulsar, Envoy,
  Istio rules to include {{ $labels }} and {{ $value }} template vars
- Downgrade Cassandra key cache hit rate: critical → warning

Comments:
- Add note on node_vmstat_oom_kill gauge type (delta vs increase)
- Add note on systemd_socket_refused_connections_total gauge type
- Add note on mysql_global_status_* gauge type (delta/deriv vs rate)
- Add note on pg_txid_current requiring a custom postgres_exporter query
- Add note on pg_stat_ssl_compression availability (PG 9.5-13 only)
- Add note on cert-manager legacy metric name for users on v1.18 and older
- Add threshold rationale for Elasticsearch, Cassandra, CouchDB rules
- Add note on NATS leaf node spurious fires when leaf nodes not configured

* fix(data): PromQL type fixes, job filter cleanup, query correctness review

- Replace rate()/increase() with deriv()/delta() on gauge metrics:
  node_vmstat_pgmajfault, cassandra_stats (criteo exporter),
  gitlab_ci_pipeline_failure_reasons, flink_taskmanager_job_task_numRecordsIn
- Fix histogram_quantile on non-_bucket metric: cilium_policy_implementation_delay
- Fix Thanos bucket replicate latency: use _count instead of _bucket for guard clause
- Fix Thanos query latency: use _count instead of _bucket for guard clause
- Restore job filter in Thanos objstore guard clauses (compact + store)
- Remove redundant job= filters from unique metrics: ~30 Thanos rules,
  kube_persistentvolume_status_phase, otelcol_process_runtime_*
- Fix high-cardinality Istio latency grouping (drop source labels from by())
- Add division-by-zero guard to host context switch ratio
- Raise noisy ClickHouse thresholds: RejectedInserts > 2, DelayedInserts > 10
- Remove redundant for: 1m from HAProxy check failure rules
- Add job rename comments to up{job=...} rules (Hadoop, OpenStack, SNMP, OTel)
- Remove external mixin references from comments
- Fix Tempo dropped spans metric name: add missing _total suffix
- Fix Thanos bucket replicate run latency: add missing le label in by()

Feature/cert manager rules (#524) 
* Add .worktrees/ to .gitignore

* feat: add cert-manager alerting rules (4 rules)

Add Prometheus alerting rules for cert-manager under the
"Network, security and storage" category:
- Cert-Manager absent (service down detection)
- Certificate expiring soon (21-day threshold)
- Certificate not ready (readiness check)
- Hitting ACME rate limits (rate limit detection)

Based on imusmanmalik/cert-manager-mixin and official
cert-manager metrics documentation.

* docs: add cert-manager to README
