Tab alignment and placement options

You can now finetune how your tabs look and behave using theme.tabs in docs.yml. Choose between the default underline or bubble style, place tabs in the header or sidebar, and center-align header tabs from a single configuration block.

theme:
  tabs:
    style: bubble
    alignment: center
    placement: header

The existing string shorthand (e.g., theme.tabs: bubble) continues to work for simple style changes.
