embed v0.4.0

Added

• group-events="series,multipart" attribute: in layout="cards", collapses
  events sharing the same partOf.id into a single stacked card with a
  mandatory "Series"/"Multi-part" badge. The header card is always the
  group's next upcoming occurrence (or the most recent past one if none are
  upcoming). Opt-in only — absent by default, so existing embeds are
  unaffected. list and calendar layouts are unchanged; every occurrence
  keeps rendering individually there.
• The detail modal gains prev/next navigation and an "N of M" counter when
  opened from a grouped card, letting a viewer step through every occurrence.
• PreviewEvent.id and PreviewEvent.partOf (from @opentechevents/preview-feed)
  are now first-class fields, alongside the existing id detail row.
• EventRenderContext.group exposes { key, type, index, total, members }
  for the currently-rendered occurrence, so host apps (e.g. the editor's own
  eventActions) can react to group membership. ote-event-action's DOM
  event detail carries the same group field when applicable.
• Past occurrences (only reachable with show-past="true") now render at
  reduced opacity in list/cards layouts, so upcoming events stand out.
• fields-preview and fields-detail attributes let you configure the card
  (preview) and the detail modal/list-body independently, instead of the
  single fields attribute controlling both. fields still works as a
  shared fallback for both when the specific attribute is absent, so
  existing embeds are unaffected.
• eligibility and cfp are now captured from OTE feeds (via
  @opentechevents/preview-feed) and rendered as small, linkable badges —
  e.g. "Members only" or "Call for Proposals" — wherever fields/
  fields-preview/fields-detail includes them. Off by default on the card
  (same opt-in policy as group-events), but shown by default in the detail
  modal along with every other optional field.
• A priced event's badge now links to its registration/ticket URL when the
  winning offers[] entry has one (PreviewEvent.price.url).
• card-width attribute ("small"/"medium"/"large", or any raw CSS
  length) and the underlying --ote-card-min-width CSS custom property
  control the minimum card width — and so, responsively, the column count —
  in layout="cards". Default (220px) is unchanged.

Fixed

• The detail modal now closes on Escape. The keydown listener already
  existed but nothing ever moved focus into the modal, so the key never
  reached it; opening a modal now focuses its close button.
• Markdown inline formatting is now recursive: a link nested inside
  **bold** or *italic* (e.g. **see [our calendar](https://...)**) now
  renders as an actual link instead of literal [text](url).
• Numbered lists (1. , 2. ) in Markdown descriptions now render as <ol>
  instead of showing the literal 1. prefix as plain text.
• Markdown descriptions are now rendered with marked (the same
  CommonMark+GFM parser the editor's own preview uses) instead of a hand-rolled
  line-based parser, with DOMPurify sanitizing the result since feed
  descriptions come from a remote, untrusted source. Headings (### ...) were
  previously stripped down to plain paragraph text; they now render as real
  <h1>-<h6> elements. A sub-list nested inside a list item (e.g. a bullet
  list under one step of a numbered list) previously got flattened into a
  separate sibling list; it now stays correctly nested.
• The detail modal now respects field configuration (fields/
  fields-detail) instead of always rendering every optional field
  unconditionally, regardless of what the card was configured to show.
• The location field no longer echoes the attendance badge's "Online" label
  for an online event with no link (now "No public link", with a title
  tooltip noting the organizer may share it privately), and no longer wrongly
  claims "Online" for an in-person/hybrid event with no venue (now "Venue not
  specified"). Both were symptoms of the same upstream fallback in
  @opentechevents/preview-feed defaulting to a generic "online" location
  whenever a source gave no venue and no URL, regardless of the event's
  actual attendanceMode.
