Social Cards for Matheology
*****************************************************************

When you share a link to a matheology page on social media (Twitter/X,
Facebook, LinkedIn, Slack, Discord, etc.), the platform shows a **social card**
--- a preview with a title, description, and image. These cards are the first
thing most people see, so they matter.


What Is a Social Card?
========================

A social card is generated from metadata in each page's HTML header. When
someone pastes a link, the platform reads:

- **og:card:title** --- the bold headline on the card (35--45 characters)
- **description** --- the text below the title (140--150 characters)
- **og:card:image** --- the preview image (auto-generated at 1146 x 600 px)

These fields are set via ``.. meta::`` directives at the top of each RST file.
The site's build system (``sphinxext-opengraph``) converts them into the
standard Open Graph tags that social media platforms expect.


Example: The Matheology Landing Page
=======================================

Here is what the social card for the main matheology page looks like when
shared on social media:

.. image:: /_file/image/about/socialcard/summary_matheology_socialcard_example.png
   :alt: Social card for the Mathematical Theology landing page, showing the title "Mathematical Theology — Axioms, Common Ground" and description.
   :width: 600px

The fields that produced this card:

.. list-table::
   :widths: 30 70

   * - **Title**
     - Mathematical Theology --- Axioms, Common Ground
   * - **Description**
     - Matheology uses axiomatic logic to find where theological traditions
       that waged war for millennia actually agree once stated precisely.

This card is crafted to:

1. **Be self-explanatory** --- the title alone tells you what the page is about
2. **Hook the reader** --- the description makes you want to click
3. **End at natural boundaries** --- no mid-word truncation on any platform
4. **Be accurate** --- the description matches what you actually find on the page


Coverage
=========

Every page in the matheology section (~245 pages) has social card metadata.
