SleekMate / Documentation — no list of available variables for email templates

Expected Behavior The documentation or the SleekMate chat assistant should provide the full list of available variables (e.g., {{username}}, {{posttitle}}) that can be used when customizing email templates, along with a description of what each variable renders. Current Behavior Neither the documentation nor SleekMate mentions the available variables for email templates. When customizing a template, there is no reference to know which variables are supported, making it impossible to personalize emails without trial and error. Possible Solution Add a dedicated section in the documentation listing all supported variables for each email template type, with examples of rendered output. And/or have SleekMate able to answer questions like "what variables can I use in email templates?" Steps to Reproduce Go to the Sleekplan admin dashboard. Navigate to the email templates customization section. Try to find the list of available variables in the documentation or by asking SleekMate. Observe that no such list is provided anywhere. Context (Environment) Affects any admin trying to customize email templates without prior knowledge of the available variables. SleekMate is unable to answer questions on this topic.
