What happened?

Two separate spacing gaps, both on the light theme on macOS.

1. Compose window: Send toolbar has no top padding, collides with the title bar

In liquidbird.css:

#composeToolbar2 {
  min-block-size: 36px !important;
  padding-inline: 8px !important;
  padding-block-end: 5px !important;   /* bottom only, no top */
  gap: 2px !important;
}

#composeToolbar2 gets padding-block-end but no padding-block-start, so on macOS the Send / Encrypt / Spelling / Save / Contacts row sits hard against the native window title bar, roughly 2px of gap. Every other row in the compose header (From, To, Subject) has comfortable spacing; only the toolbar is cramped.

Note: naively adding padding-block-start to #composeToolbar2 makes it worse. The toolbar shifts upward and overlaps the title text. The fix looks like it belongs on #compose-toolbox or a titlebar spacer, not on #composeToolbar2 itself.

Expected: the toolbar gets the same vertical breathing room the rest of the compose header has, clearly separated from the title bar.

2. Task list: rows have border-radius but the tree has no inset

In liquidbird.css, around line 1428:

#cards tr,
#task-tree tr,
.calendar-event-box-container,
.conversation-list-item {
  border-radius: var(--lb-radius-small) !important;
}

#task-tree tr gets a border-radius, but #task-tree has no padding and the rows have no margin, so the rounded rows butt against the pane edges with no gap and the rounding is effectively invisible. Compare #folderTree, which has padding: 3px 7px 12px so its rounded rows sit inside with room.

Expected: a small inset on #task-tree (and probably #cards for the address book, which shares the rule), matching the folder tree.

Reproduction steps

Compose toolbar:

1. Enable LiquidBird on macOS, light appearance.
2. Open a new compose window.
3. The Send / Spelling / Save toolbar row sits flush against the window title bar.

Task list:

1. Open the Tasks space (or the Tasks panel in the mail window).
2. The task rows run edge to edge with no inset; the row border-radius has no visible effect.

Other customizations and add-ons

Personal custom.css has rules for the 3-pane mail list, folder tree, and tabs only. Nothing in it touches the compose window or the task pane, and the two rules cited above are LiquidBird's own. Installed add-ons (Thunderbird Conversations, CardBook, Compact Headers, Send Later, Markdown Here Revival) do not restyle either area.

Isolation checks

• I reproduced this with personal custom.css rules removed, if practical.
• I confirmed that disabling LiquidBird removes the problem, if practical.
• I removed personal data from everything attached to this report.
