v0.4.0

Breaking: DOM changes that affect downstream selectors

A resource's own URI is a link, not a <code> element

The first row of every *Infobox rendered <dd><code>{{resourceURI}}</code></dd>.
It now renders the URI as a link opening in a new tab, emitted by a new shared
resourceUriRow block: <dd class="esbResourceUri"><a class="esbExtLink" …>. The
<code> element is gone, so a selector reaching for it — or code relying on the
browser's default monospacing — needs .esbResourceUri instead. The link is not
assumed to stay within the portal.

The parent terminology or data vocabulary is linked from the header

Concept, class and property pages now link their parent from the page header: a
concept its terminology (skos:inScheme, esbTerminologyLink), a class or property
its data vocabulary (rdfs:isDefinedBy, esbDatavocLink). The <br/> that
separated the publisher link from the type badge in header is dropped along with
it, so a host that positioned the badge off that line break needs its own rule.
specHeader has its own template and is unaffected.

Link hooks from relatedLink sit on the <a>, not on a wrapper

relatedLink's class parameter is renamed linkClass and reaches the anchor
rather than the wrapping element. esbTerminologyLink, esbDatavocLink and
esbSpecLink previously landed twice — on the <dd> (or the mount <span>) and on
the <a> within it — doubling any ::after icon or boxed styling built on them.
Each appears once now, on the <a>, as esbOrgLink, esbClassLink and
esbConceptLink already did. A selector matching the wrapper (dd.esbDatavocLink)
has to move to the anchor. apRelated's microformats u-url moves with it, onto
the element carrying the href, where a parser expects it.

A resource descriptor's "Role" label is visually hidden

The <dt> for prof:hasRole in the esbResourcesFeatures list carries sr-only,
keeping the label for screen readers without showing it. The bundle does not define
.sr-only; the host stylesheet has to, as it already must for the runtime's own
live regions and for this block's expand-button label.

Breaking: specMain no longer renders the diagram and AP button

specMain opened with diagramImage and specInspectAPButton. Both now sit behind
a new standAlone parameter, default false, so a page that wants them has to ask:
standAlone="true" on specMain, or on specView, which forwards it. This lets a
host lay the two blocks out itself — demo/ap.html already mounts diagramImage
directly — but a host mounting specView and expecting the previous output has to
set the parameter.

Added

• A new block, resourceUriRow: the shared first row of every *Infobox,
  taking the <dt> wording as dtContent.
• New esb* classes: esbResourceUri, esbExtLink and esbTerminologyLink.
  All three are described in the README.
• A new parameter, standAlone, on specMain and specView (above).

Removed

• relatedLink's class parameter, renamed linkClass (above). At a mount
  point that is data-entryscape-link-class.

Fixed

• The concept infobox's terminology link carries an esb* class. It emitted a
  bare terminologyLink, outside the convention and undocumented; it is
  esbTerminologyLink now, the class the header's parent link also uses.
