+/**
+ * @brief LLGS — Easter egg by Arturo Balam (Data - 7A)
+ *
+ * Opcode: 0x0F1
+ *
+ * Writes a Spider ASCII art into RAM starting at address 0x00,
+ * and loads the author signature into RA as a packed ASCII string.
+ * This version matches the custom mechanical spider design
+ * and is formatted to fit an 8-byte RAM viewer width.
+ *
+ * RAM layout after LLGS executes (8 characters per row, 4 rows total):
+ * 0x00:  "// _ \\"   (Row 1)
+ * 0x08:  "\\( )// "   (Row 2)
+ * 0x10:  " //()\\ "   (Row 3)
+ * 0x18:  " \\  // "   (Row 4)
+ *
+ * RA after execution: 0x4C4C475300000000ULL ("LLGS" in ASCII, zero-padded)
+ * (L=0x4C, L=0x4C, G=0x47, S=0x53)
