django-countdown 0.2.0

Added

• i18n: every user-visible string now flows through gettext_lazy /
  {% trans %}, with full Polish translations shipped in
  django_countdown/locale/pl/LC_MESSAGES/django.{po,mo}.
• manage.py start_countdown management command — interactive by
  default (asks how long the banner shows, then how long service mode
  lasts), or non-interactive via --banner +5m --service +30m --message … --noinput. Service duration accepts indefinite/forever/inf to
  keep the site blocked until an admin removes the countdown.
• Indefinite maintenance mode: when maintenance_until is None the
  site stays blocked indefinitely. New SiteCountdown.is_indefinite()
  helper + admin column; banner and blocked templates render an
  "indefinite — remove the countdown to unblock" affordance instead of a
  broken counter.
• CSS-framework-agnostic blocked-page themes: three variants —
  blocked.html (plain, default — ships its own stylesheet, no Bootstrap
  / Foundation / Tailwind required), blocked_foundation.html,
  blocked_bootstrap.html — all extending a shared blocked_base.html
  so themes inherit translations automatically. Pick one via the new
  DJANGO_COUNTDOWN_BLOCKED_TEMPLATE setting.
• Example app discovery page: the example project now has a real
  / page listing all template variants with one-click previews
  (/preview/<plain|foundation|bootstrap>/[indefinite/]) and a
  /healthz/ endpoint for confirming the middleware blocks correctly.
• SiteCountdown model + admin (extracted from
  iplweb/bpp @ 75f3c70f7) with
  countdown_time and optional maintenance_until.
• CountdownBlockingMiddleware returning HTTP 503 for non-superuser
  requests once the countdown has expired and maintenance has not yet
  ended.
• countdown_context context processor exposing active_countdown /
  maintenance_countdown to templates.
• Template partials: countdown_banner.html and blocked.html.

Changed

• countdown_banner.html no longer depends on django-compressor; it
  just {% static %}-loads the package stylesheet.
• blocked.html no longer pulls Foundation Sites or foundation-icons by
  default. Use blocked_foundation.html if you want that look.
• All hard-coded Polish field labels, help-texts, and admin headings in
  the model + admin migrated to English as the source language, with
  Polish kept as a first-class translation.

Fixed

• admin.time_remaining_display two format_html() calls with no
  substitutions raised TypeError on Django 6.0 (strict signature).
  Replaced with mark_safe() for the literal-HTML branches.

Migrations

• 0005_alter_sitecountdown_options_and_more.py records the English
  field metadata. Running migrate is required after upgrading.
