+# 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`.

 .SYNOPSIS
-  Build and deploy the Lean 101 Clients app to a Digital Ocean droplet over SSH.
+  Deploy the Lean 101 Clients app to a Digital Ocean droplet over SSH.
 
 .DESCRIPTION
-  Runs `docker compose` against `docker-compose.production.yml` on the remote
-  host. The same script handles first-time bootstrap and subsequent updates:
+  Tars the local source tree, uploads it to the droplet, and runs
+  docker compose up --build. No git required on the server.
 
-    * On bootstrap (-Bootstrap): creates the remote directory, clones the
-      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).
+  The same script handles first-time setup and subsequent updates.
 
 .PARAMETER RemoteHost
   Hostname or IP of the Digital Ocean droplet. Required.
 
 .PARAMETER RemoteUser
-  SSH user on the droplet. Defaults to `root`.
+  SSH user. Defaults to 'root'.
 
 .PARAMETER RemotePath
-  Absolute path on the droplet where the repo lives. Defaults to
-  `/srv/lean101-clients`.
-
-.PARAMETER Branch
-  Git branch to deploy. Defaults to `main`.
-
-.PARAMETER RepoUrl
-  Git URL used during bootstrap when the remote directory is empty.
-  Required only with -Bootstrap.
+  Absolute path on the droplet. Defaults to '/srv/lean101-clients'.
 
 .PARAMETER EnvFile
-  Local path to the env file that should land on the droplet as
-  `<RemotePath>/.env.production`. Defaults to `.env.production`.
+  Local path to the production env file. Defaults to '.env.production'.
 
 .PARAMETER SshKey
-  Optional path to an SSH private key. If omitted, the script relies on
-  ssh-agent / default keys.
+  Optional path to an SSH private key.
 
 .PARAMETER ComposeFile
-  Compose file name on the remote host. Defaults to
-  `docker-compose.production.yml`.
-
-.PARAMETER Bootstrap
-  Run first-time setup (clone, upload env, build, up).
-
-.PARAMETER SkipBuild
-  Pass `--no-build` to docker compose (use when only env changed).
+  Compose file name on the remote host. Defaults to 'docker-compose.production.yml'.
 
 .PARAMETER Seed
-  Run `python -m app.seed` inside the backend container after the stack is up.
+  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.
+  Tail logs for ~60 lines after deploy to verify the stack came up.
+
+.PARAMETER SkipBuild
+  Pass --no-build to docker compose (use when only env changed).

-  ./deploy/Deploy.ps1 -RemoteHost 203.0.113.10 -Bootstrap -RepoUrl git@github.com:ponzischeme89/data-entry-app.git

+# migrate-to-postgres.sh
+#
+# Migrates the lean101-clients production stack from SQLite to PostgreSQL.
+# Safe: backs up everything before touching anything. Old stack stays live
+# until you confirm migration succeeded.
+#
+# HOW TO USE:
+#   1. Copy this file to the server:
+#      scp deploy/migrate-to-postgres.sh root@<host>:/srv/lean101-clients/deploy/
+#
+#   2. SSH in and run it directly (must be interactive — not piped):
+#      ssh root@<host>
+#      bash /srv/lean101-clients/deploy/migrate-to-postgres.sh
