-**Usage:**
-
-```jsx
-<SchemaTableCompact
-  name="Locations"
-  description="Stores geographic location data."
-  status="implemented"
-  columns={[
-    { name: 'LocationID', type: 'int', pk: true, description: 'Primary key' },
-    { name: 'Name', type: 'nvarchar(200)', description: 'Location name' },
-  ]}
-/>
-```
-
-**Props:**
-
-<TableVerticalNoRef
-  alt="Table: Prop, Type, Required, Description"
-  headers={[[{ value: 'Prop' }, { value: 'Type' }, { value: 'Required' }, { value: 'Description' }]]}
-  columns={[
-    ['<code>name</code>', '<code>description</code>', '<code>status</code>', '<code>columns</code>', '<code>notes</code>', '<code>jsonSchemas</code>', '<code>id</code>'],
-    ['String', 'String', 'String', 'Array', 'String', 'Array', 'String'],
-    ['Yes', 'No', 'No', 'Yes', 'No', 'No', 'No'],
-    ['Table name', 'Table description', '<code>"implemented"</code> (default), <code>"partial"</code>, or <code>"planned"</code>', 'Array of column definition objects', 'Additional notes', 'JSON schema examples', 'Custom HTML id'],
-  ]}
-/>
-

-
-### SchemaTag
-
-**Purpose:** Inline colored tag/badge for labeling schema elements (e.g., primary keys, foreign keys, data types).
-
-**Import:**
-
-```jsx
-import SchemaTag from '@site/src/components/SchemaTag';
-```
-
-**Usage:**
-
-```jsx
-<SchemaTag type="pk">Primary Key</SchemaTag>
-<SchemaTag type="fk" href="#locations-table">LocationID</SchemaTag>
-```
-
-**Props:**
-
-<TableVerticalNoRef
-  alt="Table: Prop, Type, Required, Description"
-  headers={[[{ value: 'Prop' }, { value: 'Type' }, { value: 'Required' }, { value: 'Description' }]]}
-  columns={[
-    ['<code>type</code>', '<code>children</code>', '<code>href</code>', '<code>title</code>'],
-    ['String', 'Node', 'String', 'String'],
-    ['Yes', 'Yes', 'No', 'No'],
-    ['Tag style type (e.g., <code>"pk"</code>, <code>"fk"</code>)', 'Label content', 'If provided, renders as a link', 'Tooltip text'],
-  ]}
-/>
-
----
-
-### SchemaRelationshipDiagram
-
-**Purpose:** Data-driven entity relationship diagram rendered with CSS flexbox, showing table relationships within DST database modules.
-
-**Import:**
-
-```jsx
-import SchemaRelationshipDiagram from '@site/src/components/SchemaRelationshipDiagram';
-```
-
-**Usage:**
-
-```jsx
-{/* Show all modules and relationships */}
-<SchemaRelationshipDiagram />
-
-{/* Filter to a single module */}
-<SchemaRelationshipDiagram moduleId="common" />
-```
-
-**Props:**
-
-<TableVerticalNoRef
-  alt="Table: Prop, Type, Required, Description"
-  headers={[[{ value: 'Prop' }, { value: 'Type' }, { value: 'Required' }, { value: 'Description' }]]}
-  columns={[['<code>moduleId</code>'], ['String'], ['No'], ['Filter diagram to a single module. When omitted, all modules are shown.']]}
