READ PAGE (List View) – list_characters.php  → the "R" in CRUD
---------------------------------------------------------------
Pattern is the same as Skellig films-read example:

  1. Connect to the database.               ✅
  2. Run a SELECT query.                    ✅
  3. Loop through the result set.           ✅
  4. Output a card/div for each record.     ✅
  5. Provide Edit/Delete links for each.    ✅

This page reads from:
  - t_characters (PK: character_id, FK: role_id)
  - t_roles      (PK: role_id)
and joins them so we can show the role NAME, not just the ID.
--------------------------------------------------------------->

<?php
require "includes/db.php";
// includes/db.php opens the MySQLi connection and assigns it to $conn.

/*
 * STEP 2 ✅ Run a SELECT query (READ).
 * - t_characters: PRIMARY KEY is character_id
 * - t_roles:      PRIMARY KEY is role_id
 * - role_id in t_characters is used as a FOREIGN KEY to t_roles.role_id
 */
$sql = "
    SELECT c.*, r.role_name
    FROM t_characters AS c
    INNER JOIN t_roles AS r
        ON c.role_id = r.role_id   -- FK (c.role_id) → PK (r.role_id)
    ORDER BY c.character_name ASC
";

$result = mysqli_query($conn, $sql);

if (!$result) {
    die("Query error: " . mysqli_error($conn)); // Basic error handling if the SELECT fails.
}

/*
 * Array of stat fields + labels.
 * This avoids repeating the same HTML block 6 times, i.e. the DRY principle (Don't Repeat Youself).
 */
$stats = [
    "health"   => "HP",
    "defense"  => "DEF",
    "strength" => "STR",
    "magic"    => "MAG",
    "speed"    => "SPD",
