[DÚVIDA] Como o método store() está sendo executado?

Bom dia! Tudo está funcionando normal aqui conforme a aula, porém não entendi como o store() do LoginController está sendo executado - visto que não definimos um action no formulário de login.

Por que o store() está sendo executado?

index.blade.php:

<x-layout title="login">
    <form method="post">
        @csrf
        <div class="form-group text-light">
            <label for="email" class="form-label">E-mail</label>
            <input type= "email" name="email" id="email" class="form-control">        
        </div> 

        <div class="form-group text-light">
            <label for="password" class="form-label">Password</label>
            <input type= "password" name="password" id="password" class="form-control">        
        </div> 

        <button class="btn btn-primary mt-3">
            Entrar
        </button>

    </form>
</x-layout>

LoginController:

<?php 

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Request;



class LoginController
{
    public function index()
    {
        return view('login.index');
    }

    public function store(Request $request)
    {
        if (!Auth::attempt($request->all()));
    }
}

Rotas:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\SeriesController;
use App\Http\Controllers\SeasonsController;
use App\Http\Controllers\EpisodesController;
use Illuminate\Http\Request;
use App\Http\Middleware\Autenticador;
use App\Http\Controllers\LoginController;


Route::get('/', function () {
    return redirect('series');
})->middleware(Autenticador::class);

Route::resource('/series', SeriesController::class)
    ->except(['show']);

Route::get('/series/{series}/seasons', [SeasonsController::class, 'index'])->name('seasons.index');

Route::get('/seasons/{season}/episodes', [EpisodesController::class, 'index'])->name('episodes.index');

Route::post('/seasons/{season}/episodes', [EpisodesController::class, 'update'])->name('episodes.update');

Route::get('/login', [LoginController::class, 'index'])->name('login');

Route::post('/login', [LoginController::class, 'store'])->name('signin');
