Layout Card

Good afternoon everybody,

I know I’m really stupid and I apologize in advance, but I really don’t understand how to create my dashboard how I want and I was wondering if I could get some advice.

trying to create a panel for work that I have a feature but I’m not getting it

Here is a crude paint drawing of what I would like to achieve.

type: custom:layout-card
layout_type: grid
layout:
  grid-template-columns: 33% 63%
  grid-template-rows: auto
  grid-template-areas: |
    "header header"
    "main main2"
cards:
  - type: vertical-stack
    cards:
      - type: entities
        title: Tomada Sala
        entities:
          - entity: switch.tomada_sala_soquete_1
            name: Energia
            icon: mdi:lightning-bolt
    view_layout:
      grid-area: header
  - show_name: true
    show_icon: true
    type: button
    tap_action:
      action: toggle
    icon: mdi:television
    name: Tv Sala
    entity: switch.tomada_tv_soquete_1
    show_state: true
    view_layout:
      grid-area: main
  - type: custom:mini-graph-card
    entities:
      - sensor.tomada_sala_potencia
    name: Wats
    hours_to_show: 168
    points_per_hour: 0.25
    grid-area: main2
  - type: custom:layout-card
    layout_type: grid
    layout:
      grid-template-columns: 50% 50%
      grid-template-areas: |
        "card1 card2"
    cards:
      - type: entities
        entities:
          - entity: sensor.example1
        view_layout:
          grid-area: card1
      - type: entities
        entities:

        view_layout:
          grid-area: card2
  - type: custom:layout-card

        "card3 card4 card5"
    cards:
      - type: entities
        entities:
          - entity: sensor.example3
        view_layout:
          grid-area: card3
      - type: entities
        entities:
          - entity: sensor.example4
        view_layout:
          grid-area: card4
      - type: entities
        entities:
          - entity: sensor.example5
