as a next step, i'll fetch the docker image from the google registry, and see what memory and disk usage looks like when i run it locally.

running into this as i continue to grow my labor data warehouse.

Here a CloudRun PM says the container size should not count against memory: https://stackoverflow.com/a/56570717

Here is some working javascript code. There might be better solution, I'm not a JS expert. ```javascript var show_hide = document.querySelector(".show-hide-sql > a");

// Hide SQL query if the URL opened with #_hide_sql
var hash = window.location.hash;
if(hash === "#_hide_sql") {
    hide_sql();
}
show_hide.setAttribute("href", "#");
show_hide.addEventListener("click", toggle_sql_display);

function toggle_sql_display() {
    if (show_hide.innerText === "hide") {
        hide_sql();
        return;
    }
    if (show_hide.innerText === "show") {
        show_sql();
        return;
    }
}

function hide_sql() {
    sql_element.style.cssText="display:none";
    show_hide.innerHTML = "show";
    show_hide.setAttribute("href", "#_hide_sql");
}

function show_sql() {
    sql_element.style.cssText="display:block";
    show_hide.innerHTML = "hide";
    show_hide.setAttribute("href", "#_show_sql");
}

```

Turns out this already works - __bool__ falls back on __len__: https://docs.python.org/3/reference/datamodel.html#object.bool

When this method is not defined, __len__() is called, if it is defined, and the object is considered true if its result is nonzero.

I'll add a test to demonstrate this.
