用户要求将底部导航栏的高度减半。目前底部导航栏的高度是78px（包括pt-3 pb-7），需要将其减半调整。
让我看看当前的底部导航栏结构：
- `height: 78px`
- `pt-3 pb-7`（padding-top: 0.75rem, padding-bottom: 1.75rem）
- 加号按钮 `margin-top: -19px`
- 按钮尺寸 50x50
如果高度减半，大约是39px。但考虑到加号按钮需要空间，还有下方的home indicator，我需要合理调整。
目前78px高度中，pt-3是12px，pb-7是28px，加上按钮和内容区域。减半后大约39-40px。
按钮目前是50x50，margin-top: -19px让按钮一半悬浮在上方。如果底部栏高度减半，按钮可能需要调整。
让我重新设计：
- 底部导航栏高度约40px
- padding减少
- 按钮可能需要更紧凑
- 文字和图标可能需要缩小
考虑到底部导航需要容纳加号按钮（50x50，一半悬浮即25px在导航栏内），加上底部home indicator（约4px + 间距），导航栏至少需要约35-40px的有效内容区域。
让我将height改为约44px，减少padding。加号按钮保持50x50但调整margin-top使其更紧凑。
实际上用户说"减半"，当前78px减半约39px。让我设计为约42-44px，这样有足够的空间容纳按钮和文字。
我需要调整：
1. 容器高度从78px → ~44px
2. padding从pt-3 pb-7 → pt-1.5 pb-1.5
3. 加号按钮margin-top调整
4. 按钮和图标可能需要缩小一点
5. home indicator位置调整
让我也稍微缩小加号按钮从50px到44-46px以匹配更紧凑的布局，或者保持50px但调整位置。
考虑到用户只说了"减半调整"，我理解为将底部导航栏的高度减半。当前是78px，减半到约39-42px。按钮50x50，需要有一部分突出到上方，所以实际内容区域大约需要30-35px空间给文字和图标，按钮突出部分在上方。
让我重新设计：height约42px，内容区域紧凑排列。加号按钮保持50x50，margin-top调整使得它有一半（约25px）在导航栏内，约25px突出在上方。底部导航内容（文字+图标）大约25-30px高。
实际上用更简单的方式：将height改为40px，pt-1 pb-1.5，按钮margin-top调整。按钮可以稍微缩小到46px。
让我简化：height: 42px，按钮保持50x50，margin-top: -22px。这样按钮有28px在栏内，22px突出。底部home indicator放在bottom-0.5。
nav-item的图标和文字保持17px和13px，但在更紧凑的空间内排列。
好的，让我输出精简后的代码。

summary
底部导航栏高度从78px减半至42px：内边距从pt-3/pb-7压缩为pt-1/pb-1.5，加号按钮margin-top微调至-21px，home indicator上移至bottom-0.5，整体导航栏更紧凑轻量，释放更多主内容区域空间。
