Issue 1 — cursor lies about armed tool. .svg-draggable { cursor: grab }
on frame/device rects beat the .canvas-wrap.tool-device #canvas {
cursor: crosshair } rule because element-level wins over descendant.
m saw "grab" hovering a frame with +Dev armed and thought the tool was
broken even though clicks routed correctly after the previous fix. Add
a descendant rule with !important so tool-armed wraps any child cursor:
.canvas-wrap.tool-frame #canvas *,
.canvas-wrap.tool-device #canvas * { cursor: crosshair !important; }
Issue 2 — stale browser cache after each redeploy. http.FileServerFS
served embedded assets with no Cache-Control header, so browsers held
on to the previous main.js/style.css until hard-reload. New noCache
middleware on the static handler emits Cache-Control: no-cache. Note:
embedded FS files have zero ModTime, so http.FileServer suppresses
Last-Modified — every fetch is a fresh 200 rather than a 304. Fine at
~30KB of JS+CSS, and fixes the staleness problem completely.
Middleware is wrapped only around the static handler. /api/* responses
write their own headers and aren't touched.
Verified locally:
curl -I /main.js → Cache-Control: no-cache
curl -I /style.css → Cache-Control: no-cache + contains the new rule
curl -I /api/healthz → unaffected (no Cache-Control from us)
go test -race ./... still green.
