This workspace is set up as an A0 conference poster on the Gemini theme, with a title bar and blocks for introduction, method, results, and conclusion. Tell me what the poster presents, or paste your paper, and I will draft the content into the blocks.

  \begin{block}{Introduction}
    State the problem, why it matters, and the one-sentence contribution.
    Posters are read in under two minutes: lead with the finding, not the
    background.
  \end{block}

  \begin{block}{Method}
    We minimize a regularized objective over parameters $\theta$:
    \begin{equation*}
      \hat{\theta} = \arg\min_{\theta}\;
        \frac{1}{n}\sum_{i=1}^{n} \ell\bigl(f_\theta(x_i), y_i\bigr)
        + \lambda \|\theta\|_2^2 .
    \end{equation*}
    \heading{The key idea}
    Describe the model and estimation procedure in a short paragraph, then
    note the one trick that makes it work.
  \end{block}

  \begin{alertblock}{Takeaway}
    One sentence a passerby should remember after reading nothing else.

  \begin{block}{Conclusion}
    Restate the contribution in one line, name the main limitation, and give
    a pointer to the paper or code. Ask the agent in the chat to draft the
    poster from your paper.
