Wireframe quick wins: lightbox gallery, vocab table, globe reframe

#97 - Enable lightbox for Photo Gallery: adds `lightbox: true` to
_quarto.yml. The existing `group="gallery"` attributes on all 6 images
now activate GLightbox with prev/next arrow navigation.

#100 - Improve Vocabularies table readability: replace broken auto-
generated listings with clean markdown tables. Remove redundant
collapsible callout. Add section headings for Core and Extension
vocabularies. Link extensions to their GitHub repos (pages are 404).

#77 - Globe hero reframe: raise camera to center globe in viewport
(was sitting low). Slow rotation from 15s to 18s per loop. Reduce
file size from 3.8 MB to 1.6 MB (90 frames, quality 35).

-## Taxonomies {.unnumbered}

 One of the foundations for interoperability of iSamples material sample descriptions is the definition of vocabularies for the categorization of sample type. There are three core vocabularies for different aspects of sample type: material sample type, material type, and sampled feature type. Each vocabulary is maintained as an RDF file using the SKOS vocabulary, with hierarchical relationships using [`SKOS:broader`](https://www.w3.org/2009/08/skos-reference/skos.html#broader). In order to be domain agnostic, these core taxonomies cover a small set of top level terms. The taxonomies may be extended as necessary to support more specialized domains by relating additional terms using `SKOS:broader` and `SKOS:narrower`.
 
-The iSamples taxonomies are used to characterize three fundamental concepts pertaining to physical samples:
+| Vocabulary | Description |
+|:-----------|:------------|
+| [Specimen Type](generated/vocabularies/material_sample_object_type.html) | Classifies what type of specimen the physical sample record represents |
+| [Material Type](generated/vocabularies/material_type.html) | Categorizes the composition of a physical sample |
+| [Sampled Feature Type](generated/vocabularies/sampled_feature_type.html) | Indicates what the sample is representative of |
 
-1. The **Materials Vocabulary** categorizes the composition of a physical sample ("What material is the sample composed of?")
-2. The **Sampled Feature Type Vocabulary** indicates what the sample is representative of
-3. The **Specimen Type Vocabulary** classifies what type of specimen the physical sample record represents

+The core vocabularies can be extended for specialized domains. Extension vocabularies add narrower terms beneath the core concepts using `SKOS:broader` and `SKOS:narrower`. Domain-specific extensions are maintained in the following repositories:
