v1.1.0

• Self-updates via GitHub Releases.
• New settings: accent color, heading color, second-language month names
  (None/Czech/Spanish/Polish/Vietnamese), and singular/plural event-noun
  labels driving the "Next ..." flag and "Show more" toggle.
• New ics_url shortcode attribute to show a second calendar on one page.
• The widget heading is now optional — leave it blank for no title.
• Generalized defaults for public/multi-site use — a fresh install no
  longer pre-fills any site-specific calendar or heading text; existing
  installs keep their configuration unchanged via an upgrade routine.
• Compact type scale and a native <details>/<summary> "Show more" fold
  for schedules spanning more than one month — no JavaScript.
• Address line is de-duplicated when consecutive events share a location.
• Dropped the prefers-color-scheme: dark variant.
