+# Frontend layout debugging notes
+
+## Full-height layouts inside padded shells
+
+When a child layout uses negative margins to cancel a parent container's padding, `height: 100%` is often not enough to visually fill the container.
+
+Example pattern:
+
+```css
+.parent {
+  --content-padding: 1.34rem;
+  padding: var(--content-padding);
+}
+
+.child {
+  margin: calc(var(--content-padding) * -1);
+  height: 100%;
+}
+```
+
+This can leave a visible gap at the bottom because the child is still only `100%` tall while being visually expanded outward by the negative margins.
+
+Preferred fix:
+
+```css
+.child {
+  margin: calc(var(--content-padding) * -1);
+  height: calc(100% + (var(--content-padding) * 2));
+  min-height: calc(100% + (var(--content-padding) * 2));
+}
+```
+
+Worker reasoning rule:
+
+- If a panel "almost" fills the viewport but leaves a strip equal to parent padding, inspect negative margins and the nearest padded scroll container before changing inner child heights.
+- In this app, `AppSecondaryRailLayout.svelte` sits inside `ClientShell.svelte`'s padded `.content` container, so full-height fixes should account for `--content-padding`.

+  Tars the local source tree, uploads it to the droplet, and runs
-  host. The same script handles first-time bootstrap and subsequent updates:
+  docker compose up --build. No git required on the server.

-      repo (or updates if already present), uploads the local env file, and
-      brings the stack up with `docker compose ... up -d --build`.
-
-    * On update (default): SSHes to the host, fetches the requested branch,
-      uploads a refreshed env file (if changed), then runs
-      `docker compose ... up -d --build` followed by a healthcheck.
-
-  The script never executes destructive commands without asking, except for
-  recreating containers (which preserves the named Postgres volume).
 
 .PARAMETER RemoteHost

 .PARAMETER SshKey
-  Optional path to an SSH private key. If omitted, the script relies on

-
-.PARAMETER Bootstrap
-  Run first-time setup (clone, upload env, build, up).

-.PARAMETER SkipBuild
-  Pass `--no-build` to docker compose (use when only env changed).
 
 .PARAMETER Seed
-  Run `python -m app.seed` inside the backend container after the stack is up.

 .PARAMETER Logs
-  After deploy, tail logs for ~20 lines so you can verify the stack came up.
