    When the assistant responds with a longer message including markdown markup, the UI renders it out but it ends up looking too spaced out. Can you investigate what library we're using to render the
    mark down and whether it's possible to tweak the visual spacing to keep things a little bit tighter. I'm thinking in particular headings and lists as well as the overall line height is a touch too
    big.

    ⏺ I'll investigate the markdown rendering library and spacing issues in your chat UI. Let me first explore the codebase to understand how markdown is being rendered.

    ⏺ Now let me check the Tailwind typography configuration and look for any custom CSS:

    ⏺ Perfect! I found the issue. You're using react-markdown with @tailwindcss/typography plugin (the prose classes). The spacing is controlled by Tailwind's typography plugin. Let me add custom CSS
    overrides to tighten the spacing:

    ⏺ Update(tailwind.config.js)

    19 + h2: {
    20 + marginTop: '1rem',

    24 + marginTop: '0.75rem',
    25 + marginBottom: '0.5rem',

    27 + h4: {
    28 + marginTop: '0.75rem',
    29 + marginBottom: '0.5rem',
    30 + },
    31 + h5: {
    32 + marginTop: '0.75rem',

    35 + h6: {

    47 + ol: {

    51 + li: {

    53 + marginBottom: '0.25rem',
    54 + },
    55 + blockquote: {

    ⏺ Fixed! You're using react-markdown with Tailwind's @tailwindcss/typography plugin. I've updated tailwind.config.js:14-58 to tighten the spacing by:

    • Reducing line height from default 1.75 to 1.5
    • Cutting heading margins (top: 1rem, bottom: 0.5rem for h1/h2, smaller for h3-h6)
    • Reducing paragraph and list margins to 0.5rem
    • Shrinking list item margins to 0.25rem

    The changes will take effect after restarting your dev server.
