Create text for outreach/publicity for the AI gene expression summaries.

[bobular]

We need some verbiage to communicate the new AI gene expression summary feature to non-specialist users. The back end is mainly implemented in this repo in Model/src/main/java/org/apidb/apicommon/model/report/ai/SingleGeneAiExpressionReporter.java, Model/src/main/java/org/apidb/apicommon/model/report/ai/expression/Summarizer.java, Model/src/main/java/org/apidb/apicommon/model/report/ai/expression/AiExpressionCache.java and Model/src/main/java/org/apidb/apicommon/model/report/ai/expression/GeneRecordProcessor.java

We have a front end implementation in another repository that provides a new section on the gene page. If the gene has not yet been processed (and present in our cache) the user is invited to press a button to start the AI summarisation. When the summary is complete (after about a minute) it looks like the screenshot here:

Here is our in-page help, for reference:
help="This experimental feature uses AI to help interpret the gene's expression data shown in the "Transcript Expression" section further down the page. First, the AI analyzes each individual experiment using its numeric data and metadata to generate a one-sentence summary and an estimated biological relevance score. Then, those per-experiment summaries are grouped into topics to highlight common expression patterns across experiments."

Please create a markdown file in this location:
Model/src/main/java/org/apidb/apicommon/model/report/ai/expression/OUTREACH.md
containing example outreach material for website banners, Twitter/Bluesky posts, Facebook, LinkedIn and email mail-shots to registered users. Give a few variants for each type.
