UX research into current homepage strengths and weaknesses

@tishchow and Jules are working on breakdowns of the homepage, and comparisons to similar homepages across brigades.

Let's run this research before implementing any major changes. In the meantime, I'll queue up technical research we can do to be ready to roll.

檢視目前的首頁，並依照 @tishchow 和 Jules 正在準備的拆解，與各個 brigade 中類似的首頁進行比較。記錄首頁的優點與缺點，並確認在進行重大實作之前所需的技術研究；該 issue 未指定檔案、測試或程式碼進入點。
